Amenities...no lights after 6 pm....hard to do anything in the complex....when sun goes down you cannot enjoy evening outside thus there are only few lights so you cannot do anything at the beach. It would be nice if they would have bunch of torches/light thru-out the complex....it would be reaĺly enjoyable. No food service on-site/no cooking restaurant...everything is being brought from different restaurants. Yes - it gets delivered but I would prefer a pool drink/food service. The bigger lagoon pool is not heated so it was really cold to swim in. The small pool was warm but no directional signs to find it. We just thought it was really cute on photos but reality is much different.

Did not eat at the resort. There are lots of choices outside the resort. The property is beautiful and under constant care. We had a septic smell the first night that actually made my throat hurt but this was gone the next day. The shower pressure is terrible and could benefit from new shower heads. (recommend Drivse). Could use some entertainment. Live band or DJ. This is a beautiful resort and perfect for families. I would definitely stay here again. We stayed in a 2 bedroom 2.5 bath room.

The place was great and appropriately named because it was very tranquil and relaxing. The only disappointment was that there is no spa facility and breakfast available only in your room.
