Hi! Which slides and river rides can be enjoyed by non-swimmers? I can't swim or even float, so at the end of the slides I'd like an idea of how deep the pool is that you're dropped into. Even if I'm sitting on a float, there is always the chance of it turning over which is not a big deal for everyone except non-swimmers! How deep are "Lazy River" and "The Current"? Also, my husband and I will be vacationing with our 2 year old son...do you think my husband (who can swim) can just hold our son on the river rides? Or would that not be recommended? Thanks!
