They are NOT super strick on swim wear like a water park ;due to safety reasons because, of the attractions. So NO you don't HAVE TO ABSOLUTELY have swimsuit to swim here. You can wear something that looks close to swim atire and still allowed to swim. Especially if you're referring this question for a child of yours. Hope that helped 😁
I think you are supposed to but I've seen people in shorts and t-shirts.
Yes you have to wear proper swim attire
