Years ago I had purchased a cross body purse for our trip to NYC and loved it so thought this is what I needed for DW. But I found after a week it started digging into my shoulder, yea I'm probably a wimp, but I did love it. Now I bought a Disney World backpack that has one compartment. It is smaller than the regular backpack but a bit bigger than a childs. I bought it at the gift shop at the international gateway at Epcot. But I also purchased one of those Disney wallets, so I put IDs, gift card, and money into the wallet and the bigger things in the backpack are. DD is 23 is we don't carry much and her BF comes along with us now so we all share carrying, both backpack and wallet seem to be waterproof, and we only have to open 2 things for security checks.
