This was out first stay at Grassy Flats Resort and Beach Club and wow!!! First, I would like to comment on how the staff goes out of their way to make sure you are well cared for. Everyone is so kind. And I have to say the bed (in room 208) had without a doubt, the most comfortable mattress we've ever slept on. It felt like we were sleeping on a cloud. Just incredible!!! The property is very clean and they keep the grounds nicely manicured. And last but mot least, Wilma, the resort princess...what a pretty kitty. Thank you Grassy Flats. We hope to return sooner than later.

Clean, quiet and serene resort. If you're looking to relax and chill out completely then this is the place. The staff were all super nice and helpful. Absolutely gorgeous sunrise view. The property all around is beautiful. Our room was perfect and the views from the balcony were stunning! The food and drinks were excellent and the pool and hot tub were clean and relaxing. The store on the property was very well stocked and could cook up whatever you bought from them. Would highly recommend Grassy Flats resort.
