I have heard good things about Turtle farm as well. My 2 boys (8&5) would like that too. I think they would freak out with the sting-rays. We may give it a try. I am actually leaving the boys on the ship in Jamaica if we go to margaritaville and shopping. I do not feel real comfortable taking them into town. I will only take them if we end up going to Sunset beach. They LOVE Camp Carnival and usually prefer to stay there if they have a choice. As far as Cozumel, we are going to Playa Sol. I booked through shoretrips.com. That is a beach that has everything you can imagine. (All-Incl drinks,food,beach toys,chairs.water tramp,and even a mini zoo!) I have heard the place can get crowded since some of the ships have excursions there. Even if a little crowded, my kids will probably enjoy all the fun toys and the pool. My hubby and I will enjoy the drinks!
If you decide to go there, book thru shoretrips. I paid $41 a person, and the same trip thru Carnival is like $71 a person. I hope you have a good cruise. This will be our second one. I am watching the hurricane now. I hope Galveston doesn't get blown away or flooded before we leave on the 2nd.
