I love the wallet feature. All my everything is in there and then I buy one of those plastic waterproof around the neck cell phone holders for water parks and use it all day. If you go this route you can ask for a paper scanner card when you enter the locker areas that you can use to open and close your locker without your phone which is really only an issue on Hulk and RRR. You can take your phone on every other ride.
I put my phone facing one side of the plastic case so I can access barcodes for tickets/Express passes and my resort key on the other side for Early Entry and then I can just flash one side of the case or the other depending on what I need it for.
