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 room was good overall. Very spacious and well appointed, although maintenance issues need addressing. There were issues with both toilets, albeit minor and we had a strange visitor who dropped off 24 waters to our unit the morning we were checking out. We didn't receive any water on check in and I don't know why he felt the need to bring these to the room 3 hours before checkout time, he wasnt able to answer us when we asked him! Amenities needing upgrades too. The beach volleyball is deflated, I asked for another but it didn't materialise. The beach was unusable, the biggest selling aspect of the resort for us (and prime pics on the website) so until the beach is usable I felt a bit cheated!
