We are also going to Jolly Beach Resort this February. It is cold as hell in Ohio to.
We went to Jolly last year at this time. The resort is a 3 star and the beach is a 5 star. The food is great.
Rooms are like motel 6 ( Needs updated ) but the beach is amazing !!! The pool is great , The swim up bar is not so great. Here is a couple of things you need : Bring bug spay, the mosquitoes or sand fees are BAD !!!
Bring a cup for each person with a lid and straw. They will give u a small bathroom cup for a drink. Your big cup will save u standing in line and you can fill it and take it back to your room, because last year we didn't have fridges in our room:-( Don't expect little soap or shampoo, bring your own and maybe a wash cloth or two. The little things are lacking at this resort but the location makes up for it.
Also don't book any excursions with the beach vendors, last year a few couples did and wished they had not. You are better off booking stuff thru the Hotel.
Let me know if you have anymore questions
I hope you have a great time !!!
