Excellent place to stay at especially since they have it separated into families or adults-only sections. The beach is well maintained with plenty of beach sports options.

Great Stay
The resort is small but lovely. The main restaurant had great food. The accommodations were great and it was nice to have kayaking and paddle boarding included. The only downside which the resort can’t do anything about was that the low tide starts around 430pm. Then you have to head for the pool!

The beach resort was beautiful and very nice staff. If you are looking for more to do, dont stay here. It is not close to anything and the food on the resort is very expensive. The pool is wonderful and the beach area was beautifully kept. I would recommend a couple stay here fir a quiet time away.

Overall a very nice stay!
We stayed at this hotel several times. It is very nice, It’s nice that they have a separate area for adults.
They also have 3 in house places to eat, a tiki bar for lunch, a roof top for breakfast and bar in the evening and a restaurant for dinner (didn’t go to this one though).
They include free paddle boards and kayaks.
The rooms could have better A/C, they added another portable fan and seem to be having issues with A/C, hopefully will be resolved soon. Also they don’t have room service unless you call for it.
