We're staying at the Poly in May (soooo excited! we couldn't afford it, but we got a deal). I'm wondering about the Volcano water slide. Is there a specific age you have to be to go on the slide? DS will be 5 when we go. He's not a strong swimmer, so can he wear a life jacket or can I go down the slide with him or catch him at the bottom? He has taken swimming lessons, and we're signed up for more, but I don't want a disappointed little boy.
