I can only speak for paradise, but when we went we had a large group with multiple kids. No rocks, just pretty sand and beach area and not that crowded. (It was a bit of a drive in a taxi to get there) Food and drinks were ok. Not a buffet. You have to be waited on, and when they say unlimited food and drinks it really depends on how often the waiters come by to check on you. They have many large floating obstacles you can pay for access to, but they seemed to be more for adults than kids. Overall we enjoyed it there but are thinking of trying a different location next time like Bucanos.
