I have! The music was good, the dancing was fun, the limbo was fun. If you are offended by booze consumption, don't do this excursion. Before this excursion is over there will be many drunk patrons. I didn't drink any alcohol because I don't like Tequilla, but those that did were hosed down. The snorkeling is in at least 20 feet of water. The island was lovely and hot. There is volley ball games on the island, and boats you can rent.
We have been on this excursion 4-5 times, can't remember how many.
BJKeen says it all in the message above.
We have always been back in time to do a little shopping as well.
Also, the island you visit has a very nice open air restaurant just off the beach.
We did the Fiesta Party Boat last september and had a blast. The rum punch was verrry potent. The island had paddle boat at no charge, and a giant inflatable iceburg to climb, as well as a trampoline anchored out a little way. You could pay $10 for a banana boat ride or $50 for a parasailing adventure. They also bring the punch and another drink on to the beach for you. The music was fun,as was the limbo and the "shot" of Cactus Juice you got for participating help you loosen up. Got waaayy too drunk to shop, but I did anyway...that is how I ended up buying the HUGe sombrero! It was also the first cruise day that I missed dinner in the diningroom...I think I was in bed by 7:30 that nite!
