Do you still have to buy a ticket if you can’t ride because you have heart disease

I believe it's an entry fee as there are sights to see other than rides, but id call to make sure

That's something you have to check with the box office

That's something that you would have to actually call the park about. I'm sure you still have to pay some kind of entry fee, but I doubt they'd mane you pay full price for a ticket if you aren't going to ride anything.
