Is there still a fee for those who are not going to ride any of the attractions.

Everyone pays the ticket price to get into the park even if you don't ride anything.

Exactly

Once you pay to get in the slide are free and the wave pool/beach.

Idk my opinion its the cost of paying to get in once your inside you dont have to get on the rides u can just hang out

Just the entrance fee do u have passes? Depends on the pass u have u may or may not pay for parking

I am not sure I'm sorry
