The family is heading to Disney and Universal during the crazy busy Xmas week. We did this 3 years ago and survived! I believe we carried a backpack around that time with snacks, wallets, phones, ponchos, etc. I honestly don't recall having to set it down on a ride very often, but obviously must have. I remember a few rides have a basket under the seat (like Soarin). Do you ever have to be separated from your bag on a ride? I'm thinking I'd want to be sure my money/cards and phone are on my person the entire time. Would you get a small phone crossbody for that purpose?
