We stayed at the Ziva last summer (overdue review) and loved it. The resort is beautiful, the beach was just fine for us, pool was great, food was mostly great, and the staff is amazing. We were never at an all-inclusive before and we loved this one.
We did use the Club Lounge from time to time, but it didn't have a great view, and almost all of the food and liquor were available elsewhere, so we weren't there often.
We were in a suite in building 2 (old) with an amazing ocean view and we were very happy there. I think the swim up rooms would be a lot of fun for the kids, if we go back.
