When we go to WDW, DS will be 10 3/4 and DD will be barely 6. DS loves everything about water and will do pretty much anything he is able to. DD has not tried water slides yet but last summer started sticking her face under the water with her armbands on. I am planning on doing one of the water parks later in our stay (so they still want to go to the other parks) but was wondering which one everyone would suggest....
