You're in luck. My mother-in-law worked there last summer and so we took the babies. My son at the time was 2. I was worried about the same thing. There are a couple of slides (the original ones) that are located to the right when you walk in, that willl allow you to ride with the babies. I was rellieved and had fun. Just be careful at the end when you "drop" off the side, he may go under for a minute. Just hold on tight and lift him up ASAP.
Good luck and have fun. Oh BTW - there is an awesome kids area that he will enjoy as well. They also have a mini wave pool. It's too cute.!
