Hello, sorry if this question has been asked before but I'm very confused. We're taking our first trip ever in September!!

We've planned everything out and don't think we'll need to take advantage of the "park hopper" option for the theme parks. But, we do definitely want to try out the water parks and disneyquest. My question is, can you go to multiple water parks and/or disneyquest on the same day if you don't have the park hopper option?
