My son was 2 weeks shy of being 3 on our last trip. He loved the family tube ride at TL. He was 38 inches though no one asked. There was another tube ride ( I don't remember the name) that he went on alone over in the adult rides. I went first them my DH sent DS down and them DH came down. My son sat in the tube one his own and just loved it. Same with one of the adult slides. By the end of the day the lifeguards on those 2 slides knew his name. It was his favorite park of all. We leave in 10 days and he is still talking about the water park. Have a great time.
