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.

IF you are looking for hotel with the beach...look for the other resorts. The resort is very well kept but the beach is smelly and you can't enjoy your balcony or swimming pool because of horrible smell. Sorry...but people should now.

It was fantastic, good quality, comfortable and we will happily go back. One strange downside is there is a phenomenon at the natural beach on the property that smells terrible. It’s less noticeable when the tide is high but unfortunately that’s just nature and this beach is smelly. If you have a sensitive stomach you will not have a good time. We left the property for other beaches when it bothered us and otherwise had a fantastic stay. Smell was not present in the rooms at all.

Super friendly and helpful staff. Great location for just chilling out. Green - refill water bottles provided. Our double aspect room in the adult only part of the hotel was stunning and had the quietest air-con that didn't disturb my sleep - the refrigerator still rumbled away in the night but was quietest of all the others on our road trip!! (not used to air con or a refrigerator in the bedroom at home!!)
