My husband and I went to Passion Island last September with Carnival Conquest. It was our favorite day by far. We parked ourselves under a shady tree and were waited on the rest of the day. The water is awesome and no one bothers or haggles you. They served an excellent lunch right there under a tent with all kinds of selections. The bus ride to get to the tenders was longer than we anticipated and a rough ride....but all worth it. I'm sorry, I can't remember how much it cost. We are frugal though, so it must not have been too bad.
My wife and I went to passion island. The price was relatively cheap. I think it was 65 a person. It was worth every dime. We had an amazing time and the island was beautiful. If you have ever seen a corona commercial...it looked just like that. Take this excursion. You will love it!!
