I went to TL LONG AGO! So take my words with a grain of salt.
When I went, I was little but could swim. The wave pool is fine for little ones expecially since it is a "walk in" type pool. There were tons of little ones just sitting at the walk in with their parents and they would get little waves and thought it was so fun.
Also, they can ride the lazy river with you. Other that...I really don't know!!! Sorry I am not more help.
