Can he do the follwing? then maybe
can he swim? or at least propel himself thru water with little splashing?
He can not cling to you. Is he ok in water that is very deep water where he can not touch the bottom (an neither can you) and he will have no "sides" to hold onto?
Is thiere an extra charge for this? My brother would love to do it but it would all depend on cost.
no extra charge.

we were just there last week and there is no age limit. my 4 year old did it with his arm floaties on.

Guests may not bring their own flotation devices to Disney Water Parks.
OMG, it sounds really frightening! Especially the really deep water (I swim and float very well, but the whole *sharks and other ocean creatures* below me in really deep water sounds rather terrifying). Those of you who have done it, was it scary at all??
