Great place. They have an area for families and another separate one for Adult's. Conplementary drink on the tour for the first time. Super clean and comfortable. Snack bar and beverage in the room. We got the suite for extra cost but was a neat idea.

My expectations for Grassy Flats was so high. It is a beautiful setting and the rooms are wonderful with excellent service from all staff . I would have rated excellent had it been for a few details . I was unaware when I booked months back that the rooftop bar and Rhum House Restaurant would only open from Thursday to Sunday . We arrived Tuesday and left Friday. So we ate at the Land and sea Market on our 1st evening - laid back, tasty food. The resort came to life on Thursday and both the bar and restaurant were perfect venues to enjoy the setting , such a shame we only had one night to experience this. The food at The Rhum House restaurant was simply outstanding, with our server Max who was one of the best , her knowledge of the food was spot on and she really looked after us . Great decor and ambience too. The other reasons for not an excellent rating are purely my own opinions . I found the rooms had little soundproofing, so as a light sleeper I was woken a lot and I struggled with the noise of the fridge next to the bed . However, the suite with the claw set freestanding bath was very luxurious with a lovely sea view . Just a little note to the resort - there was nowhere in the bathroom to store all toiletries etc. a small table or shelf would have been great . Jeff at the poolside bar was a great asset always cheery and accommodating with cocktails and ice . We loved the pedal kayak for 2 a great way to explore the bay . Thank you to all at Grassy Flats .

This charming little place is absolutely amazing! Room was unique, very spacious and comfortable. Our flight got in late, and the office was closing, so they came up with a great easy way to check in and rest before they opened again. On that note, the staff is extremely nice, very helpful and friendly from check in to check out. The grounds are gorgeous, they even have a little restaurant/bar with a great view, unfortunately it was closed for updates during our 3 day stay. The pool/hot tub was very clean and enjoyable, right there by the water which was so peaceful to us. There are some great activities, like kiteboarding, kayaks, etc- but I will warn y'all they do cost $$, but they seem worth it. Our only gripe was a slow elevator, but the stairs are not that bad. We will absolutely return when we are in Marathon for a family trip.

The staff was WONDERFUL! Receptive, responsive and so happy! They make your stay so special, everyone makes you feel like you are the only guest there! The bartender Jeff makes the BEST drinks, Lizzy and the office staff are all excellent. They know everything in the area that’s fun to do and the restaurants that serve the very best food. Audrey, Jasmine and the rest of the staff in the “Land & Sea Market” on the property was off the charts, 10/10 for awesome service and friendliness, and the food was consistently delicious and plentiful! The chefs were top notch. They make whatever you like and amend the dish as necessary. We wanted to eat every single meal there every day, but we knew we couldn’t because we had to experience other food while we were on our vacation. Grassy Flats has another location down the street 5 minutes away called Bongos, which is so much fun! It’s not a hotel, it’s a fun/party place with water sports and multiple bars, music, and once again, excellent food and bartenders! Jasmin was covering the bar the night we visited Bongos and her drinks are amazing! She is awesome, too! So friendly, so fun, and made us want to go to this fun party place every day! The one and only negative I would mention is that our room needed a little “TLC”. It was VERY CLEAN, which is the most important thing and all we care about. But, I do think it probably needs a couple of pieces of furniture that is in better shape but other than that, our experience was OUTSTANDING!
