Online waiver, and I would recommend calling them as well to check on age restrictions.
This may or may not help. I don't know the age of your daughter. Something to keep in mind is there is an age limit where the kids have to have you there with them at all times or they aren't allowed to jump. I think it's pretty young though, like 6, 7, 8ish. I don't imagine you're trying to sign a waiver for your preschooler and send them in without you. ; ) I've never gone into a situation and wished I'd known less about it before I went in. I have been surprised by things I didn't know so I'm just throwing it out there.
You can do it online before she goes. I did it for my children that way.
