Summary: Overall, this was a great resort with beautiful grounds! Family focused, it had fun activities for the kids and the main pool was only 4 feet helping parents to relax more! The food was also excellent at all of the restaurants. The building architecture was stunning and reminded me of Greece. The staff was super attentive and kind. The beach and main pool lounges need to be replaced as they are peeling and faulty. With this price you would expect cushion lounges. Overall, an amazing resort that I would recommend to family and friends!

Summary: Front desk staff and wait staff were great! We stayed on our way to key west and on the way back we decided to stay again. In fact as we were getting ready to leave, we couldn’t think of a reason not to stay just one more night. So we ended up staying there three nights of our five night trip. The pools were great. There was live music at the outdoor bar. The view is beautiful! Definitely will stay there again.
