Questions of the users
About Grassy Flats Resort & Beach Club
Are there any room options that allow for unobstructed views of the Gulf, particularly from a King Studio balcony? Can a request be made for a higher floor?
15 November 2024
Rooms at Grassy Flats are positioned on the oceanside, which means direct Gulf views are not available. However, both the Conch House and Wreckers House feature balconies overlooking the pool and the Atlantic Ocean. Requests for specific floors can often be accommodated, so consider making a request for the 3rd floor during booking.
What is the policy regarding cancellations or rescheduling in the event of a hurricane during a scheduled stay?
10 December 2024
In case of a hurricane, stays can be rescheduled, ensuring guests can safely enjoy their time at the resort without worries.

Yes, there is a hot tub located in the Adults Only pool area, providing a relaxing option for guests looking to unwind.
What are the operating hours for the pool and on-site bars during my stay?

Is there a fee for bringing dogs to the resort, and where are they allowed on the property?
28 February 2025

15 March 2025
There is a designated smoking area located just a short distance from the guest rooms, allowing smokers to enjoy their time without disturbing other guests.
Can I fish off the dock at the resort, or are there recommended locations for fishing nearby?
10 April 2025
Fishing directly off the dock may not be ideal due to shallow waters, but staff can suggest better fishing spots nearby for a more fruitful experience.
Do the king studios at the resort come equipped with both a microwave and fridge?
20 May 2025
While king studios do include refrigerators, microwaves are not available in these rooms.
Are there any outdoor grilling facilities available for guests to use during their stay?
