We were enjoying Margaritaville last week. You can walk from the Voyager, it's about one mile in the Island Village shopping center. You can sit at the bar and drink, or at the tables if you want to eat. They do have a pool and slide, but it wasn't used while we were there. The beach is nice, but they do charge $5.00, a small price to pay.
It was a really fun place to spend some time. The shopping area is also nice, I think it is pretty new.
