You fill out the waiver there on their screen. And to the best of my knowledge, one adult is fine for two kids. We took 3 with 2 adults and only one adult signed the waiver.
You can sign wavier yourself there or bring it and print it out And one adult is okay for 2 kids. They usually all jump together. It can be nerve racking with all the kids but so fun for the kids as well.
Easiest to fill out the waiver before you go on a computer. You can fill it out and do not have to jump. You can just be an observer if you want. Bring socks for yourself to walk in the jump area. You must purchase their socks for the jumpers. They keep them and bring them to use on future visits. Right now Group On has a great deal for jumpers.
