Summer vacation

So I’m going to Toronto for the summer with my boyfriend and two kids, I’m recently 3 months pregnant and my boyfriend and friends got plans for us all pretty much every weekend! .... Canada’s wonderland being one of them I’m guessing all I’m allowed to do it get in the water with my son right? Or go down the lazy river No water slides ect? I don’t mean crazy fast rides that flip you every way possible or go crazy fast I don’t say I’d even do that even if I wasn’t pregnant 😂
