Paradise in Paradise.

From check in, to the pool bar, to BB at the outside cabana sports area, the staff was awesome. Location is great, even during lobster mini season. Everything you could want or need you can do right there at the resort. Room was super clean and everything was just nice and relaxing. Could not recommend this place more, if you are looking for paradise in paradise.
