SOAKED is an understatement -- You WILL need a change of shoes & clothes. You MUST wear flip flops/crocs. Ripsaw Falls wasn't operating when we did our "wet" day, but Popeye -- um, I got less wet at the HRH pool then I did on that ride.
And a word to the wise -- Don't try & do everything at the parks -- spend time at the hotel -- the HRH dive in movie & pool time was SOOO good -- DS 12 played video games & swam, DS 8 & DD 7 said the HRH slide was better then Aquatic (no line & fun), DH & I loved the pool service -- good food & drink, but not pushy.
We checked in early for our FOTL and we used pool after check out from 7-9 pm on check out day (we were staying local that night).
MUMMY was THE BEST ride but too intense for the under 8 crowd.
MIB is NOT worth the wait/locker storage if you've already done WDW IMO -- If traveling w/ 2 adults it is MUCH easier to have one adult go with the kids & the other watch bags & switch off then getting the locker.
My DS 8 & DD7 both enjoyed the HULK.
I allowed my kids to run around HRH so we could all check out the memorbilia-- a real treat which they loved. Correction -- they didn't actully "run", we just rode the elevator to each floor. They weren't wild or anything...
My heart still belongs to the Mouse, but IOA/US is really worth it. Esp if the kids love rides.
