BY RYAN GOLOVERSIC, WITH MATT SEXTON, OWNER OF GRASSY FLATS RESORT AND BEACH CLUB
There is no best hotel in Marathon. There are three kinds of hotel, and knowing which kind you are booking matters more than any star rating you will find online. One kind is built for scale. One is built for a cheap bed. One is built by people who actually live here. Every one of them is the right answer for somebody, and every one of them costs you something the others hand you for free.
Matt owns one of them. I write for him. You should know both of those things before you read another word, because this whole guide runs on honesty and that starts with us. Matt has lived and worked this coastline for over twenty years, first as a professional kiteboarder, now as the owner of one of the last family-run resorts in town. When we sat down to write this, I asked him to walk me through every property on the highway, who they serve, and where the bodies are buried. What follows is that conversation, cleaned up and organized so you can book the right room for the trip you are actually taking.
What happened to Marathon's hotels
Matt's first Keys vacation was at Hawks Cay. He was five years old. There is a photo of him holding mahi next to a jet ski that looks like it drove out of 1990, because it did. He loved that place so much he eventually moved here.
That version of the Keys, quirky mom and pop properties with exceptional hospitality and an owner behind the desk, has mostly been bought out, sold out, and rolled into the same product. Matt's words, and he watched it happen door by door. Hawks Cay, Isla Bella, and Tranquility Bay, three of the most storied properties in the Middle Keys, now sit under one management group. Faro Blanco runs under another large hospitality company alongside the Courtyard Marriott. A handful of boardrooms now answer for most of the rooms in this town, and none of those boardrooms are in this town.
Here is the thing though. That model is genuinely good at what it does. The landscaping is immaculate. The pools are gorgeous. They picture-framed the property so your balcony shot looks exactly like the website shot. When you run hundreds of rooms you can afford rate managers, spas, and a marketing budget that puts you at the top of every search. Consistency is the product and they deliver it every single day.
What the model has a harder time delivering is the personal layer. The owner is rarely the person walking the property. The front desk may be well trained, but turnover is part of large-scale hospitality. The concierge desk often works inside a referral system, so recommendations can follow the easiest commercial path instead of the most local one. You can absolutely have a nice time. You may just not feel like anyone built the stay around you. Matt says it plainly: it is an absolute cash juggernaut, and it is not usually a soulful or intimate experience. Both of those things are true at the same time, and once you accept that, booking gets a lot easier.
The three kinds of lodging in Marathon
The big resorts
Hawks Cay out on Duck Key, Isla Bella, Tranquility Bay, and Faro Blanco fill the top of every search result, and they earned it. Polished, professional, big pools, real marinas, grounds built for the photo.
Book one of these when the trip is about the property itself. A milestone birthday where everything has to run on rails. A big group with mixed ages that needs a spa, a kids program, and four restaurants inside one gate. Scale is what you are paying for, and scale shows up when you need it.
Now the real tradeoffs, because the brochure will not tell you and we will.
Start with the food. Matt has a rule he applies to every operation in town, restaurants and hotels alike: you cannot do 1,200 of anything in a night and still have it be exceptional. The math forces the corners. When a kitchen has to push that much volume, the menu writes itself, ingredients get prepped days out, and scratch cooking becomes physically impossible. You will pay fine dining prices for banquet execution, and on a slammed night you can wait an hour for food that arrives tired. The room will be beautiful while it happens.
Then the people. Hospitality at scale runs on seasonal staff and constant turnover, which means the person handling your problem started recently, has no authority to actually fix it, and will not be there when you come back next year. Read the reviews of any large property in town with that lens and a pattern jumps out. The grounds score high. The service stories run hot and cold, and the difference is almost always which staff happened to be on that week. That is not a knock on the workers. It is what the model does to the workers.
Then the routing. The concierge desk at a large resort is a revenue line, so it recommends where it earns, which means you get sent to the biggest, busiest version of everything. The high-volume tiki bar. The party boat. The same circuit every other guest is running. Matt has watched people do the whole loop and go home saying they hate the Keys, and he would hate the Keys too if that circuit was all he ever saw. You can stay at a big resort and still have a great trip here. You just have to do your own navigation, because the desk is not going to send you to the good stuff.
And underneath all of it, the thing you feel but cannot photograph. These properties deliver a beautifully picture-framed version of the Keys, and the frame is the product. You could lift the whole experience and set it down in Cancun or Scottsdale and very little would change. The actual place, the working waterfront, the fishermen, the hundred years of smuggler-town character, sits right outside the gate and most guests never touch it.
If you are good with all of that, and for certain trips you genuinely should be, these properties execute the trade as well as anyone in Florida, and we mean that. Just walk in knowing what you bought.
To be clear, none of this is aimed at any single property, and Matt would be the first to tell you these operators do real things well. He has genuine affection for Hawks Cay, because a five year old at Hawks Cay is the reason he lives here at all. He will tell you Faro Blanco is legitimately cool, an old white lighthouse anchoring a working marina, and that staying there puts you next door to some of the best charter captains in town. The big groups figured out the program, and figuring out the program at that scale is its own kind of hard. The tradeoffs above are not a scorecard of individual failures. They are the physics of the model, and every property running the model, anywhere in the world, inherits them. The point of this guide is that you should inherit them on purpose, not by accident.
The budget stays
Kingsail, Coconut Cay, and a few older motels along the highway will still put your head in a bed for around a hundred bucks a night, even in summer. The reviews hover in the mid threes. The decor gave up decades ago. None of that is the point.
These rooms serve a traveler the rest of the industry pretends does not exist, and Matt will defend that traveler all day, because he used to be one. On kiteboarding trips back in the day, he and his crew stayed at exactly these kinds of motels up in Islamorada. You are here to fish or ride. You are gone at five in the morning and back after dark. Every dollar you do not spend on the bed goes to the charter, and the charter is the trip. Booked with clear eyes, a budget motel in Marathon is correct resource allocation, and some of the happiest people in the Keys are sleeping in those rooms right now.
Just know what you are buying. A bed, a shower, a place to park the boat trailer. Walk in expecting that and you will leave happy. Walk in expecting a resort and you will write the angry review the last guy wrote.
The owner-operated properties
This category is nearly extinct in Marathon. Glunz Ocean Beach Resort out on Key Colony Beach is family owned and has been for years. Grassy Flats is the other one. That is close to the entire list, and the shortness of that list tells you everything about the economics of running a small property down here. Property taxes, insurance, employee housing. The pressure to sell is constant and almost everyone has.
What survives at an owner-operated property is accountability with a face on it. At Grassy Flats, Matt is the guy who might carry your board to the beach or hop on the wakeboard with your five year old to take the photo. When a guest wants a fishing charter and our boats are booked, he personally works the phone through captains he fishes with himself until somebody is free, and he takes no commission on the referral. The market will provision your trip starting at six in the morning. The front desk calls within three days of booking to build the stay around who is actually coming. None of that scales. That is exactly why the big operators do not do it, and exactly why we do.
Our side of the ledger
What Matt is actually building
I want to step out of the neutral guide voice for a minute, because this is the part where I stop being even-handed. I have been to this property. I have watched it run. What Matt is building on Grassy Key is the thing this whole article has been quietly mourning, and he is building it on purpose.
Old Florida is disappearing. The version of this state with real character, real owners, and food someone actually cares about is being bought out one property at a time and replaced with the assembly line. Grassy Flats is a bet against that. Matt took everything he learned in twenty years of riding, teaching, and running operations on the water and built the one property he felt the Keys deserved. Not the most profitable model. The best one.
Calling it a hotel undersells it. It is a patchwork of experiences stitched into one property, and you assemble your stay however you want. The aqua park wears the kids out while Bongos does its secret club thing fifty feet away, cold drink, music, parents watching the whole show from the shade. The cable park gives athletes a real training ground and gives families the easiest entry into watersports that exists anywhere. Then the sailing, the charters, the market, the restaurants, the sandbar runs, all of it modular, all of it plug and play. Kite in the morning, sauna in the afternoon, hook and cook at night. Or none of that, and a book on the beach. The programs snap together around whoever you brought and whatever the wind is doing, and I have genuinely not seen adventures built this way anywhere else. Most resorts hand you an activities binder. This place hands you building blocks.
And underneath all of it is one thing the big operators structurally cannot buy, which is that the owner is standing in the kitchen tasting the food. Matt pays for real ingredients when the spreadsheet says not to. He stocks the market shelves himself some mornings. He demands fresh-squeezed citrus behind the bar because he is the one drinking there too. Quality at this level in this town is a choice someone has to keep making every single day against the assembly line math, and at Grassy Flats there is a specific person making it, and he lives here.
We wrote this article to help you decide, not to corner you. But be clear about what this option is. This is the local model, exceptional care, custom adventures, run by the guy whose name is on it. If that is the trip you have been trying to book, there is exactly one of these left on this island, and now you know where it is.
Fair is fair. Here is what we cost you.
We have 38 units. In season we sell out, and when we are gone we are gone. Pull up a summer weekend and you may find us priced above the big resorts down the road, because a small property where every room has at least a partial ocean view does not chase occupancy the way a 200 room operation can. Some weeks we are the expensive option on the page. There are kiteboarders who love our beach and will stay at Rainbow Bend next door when our rates run high, then ride our flat anyway. We know. We wave at them from the water.
There is no swim-up bar here. Live music ends at eight and the property goes quiet, because the whole place is built around people who want to be on the water at seven the next morning. Locals call Grassy Key the speakeasy of the Florida Keys and the name is accurate. Quiet, a little hidden, easy to drive right past.
If what you want is a big pool scene and a resort machine that runs itself, the first category will make you happier than we will, and you should book it. If you want the cheapest possible bed, the second category is yours, sincerely. We would rather point you to the right room than collect a deposit from the wrong guest.
What to ask before you book anywhere
Whoever gets your money, walk in oriented. Ask who owns the property and whether they live in Marathon. Ask what happens when you request a fishing charter, because that answer tells you whether the front desk is a concierge or a commission desk. Ask whether the water access is real, a beach you launch from, or decorative, a seawall you look at. Ask what the resort fee actually buys. At some properties it buys parking. At ours it includes the kayaks and paddleboards, which is different math.
Matt has a warning he gives everyone, and it is the single most useful sentence in this guide. People show up chasing a Jimmy Buffett fantasy that stopped being real a long time ago, get routed through the biggest properties and the busiest tiki bars by pure marketing gravity, and go home saying they hate the Keys. He would hate the Keys too if those were the only places he ever got to see. Come here with a purpose instead. Get on the water, do the adventure, find the local spots, manage your expectations on the rest, and this chain of islands is one of the best places in the world. That is not local pride talking. That is a guy who has ridden every major watersports destination on the planet and still chose to live here.
So who has the best hotel in Marathon?
The best hotel in Marathon is the one built for your trip. For the big polished resort experience, Hawks Cay and Isla Bella run that category well. For a cheap bed between fishing days, Kingsail and its neighbors are the honest answer and nobody should talk you out of it. For a small property where the owner is on the beach, the watersports are the reason the hotel exists, and every room looks at the ocean, that is us, and we would love to have you.

FAQ ABOUT Hotels in Marathon, FL
Is Marathon cheaper than Key West?
Generally yes. Marathon lodging runs from around a hundred dollars a night at the budget motels to premium rates at the large resorts, without the cruise port markup Key West carries. You will also spend less once you arrive, because the trip here is built around the water instead of a bar street.
What is the only family-owned resort in Marathon?
There are two left. Glunz Ocean Beach Resort on Key Colony Beach and Grassy Flats Resort and Beach Club on Grassy Key. Nearly every other property in Marathon now operates under a large management group.
Where do kiteboarders stay in the Florida Keys?
The Middle Keys, and most of them stay at or ride from Grassy Flats. The resort was built by a former professional kiteboarder, the flats in front of the beach are wide and protected, and the wind from November through April is consistent enough to draw riders who have traveled everywhere.
Is Grassy Key part of Marathon?
Yes. Grassy Key sits at the quiet eastern end of Marathon, about ten minutes from the airport and the center of town, with ocean on both sides.
Should I stay in Marathon or Islamorada?
Islamorada is the sport fishing capital and sits closer to Miami. Marathon is the midpoint of the chain with a regional airport, wider protected flats, and the strongest watersports conditions in the Keys. If the trip is built around being on the water every day, Marathon is the base. Our trip planner breaks down the whole chain.
