The water rides - you will get wet, not just a little wet, you will get WET. The Dudly Do Right Falls and Popeye are wonderful rides - but you will get soaked. We planned all the rides together and then went back to the hotel for the day.
So the thought of changing etc is a GREAT idea.
The only thing is - the rides are at the back of the park - so you have to walk all the way to the front for the boat.
Regardless of what it does to you plan - GO BACK AND CHANGE. Unless you don’t mind having soggy underwear and wet shoes.
