I think when people hear "backpack" many think of those massive bags that kids lug back and forth to school on their backs but honestly, backpacks come in all different sizes now. You can get the tiniest little ones that hold more than many cross-body purses can, and I personally find a bag on my back more out of my way then a purse on my hip. Ours is a great size. Fits our camera, 2 small water bottles, Crystal Light packs, sunscreen, sanitizer, and our wallets perfectly. It's light and small and is carried across one shoulder, rather than both so it's very convenient to pop on and off. Disney rides make it easy to bring bags with you wherever you go. I don't mind carrying it around at all and much prefer to have all that stuff with me for when I need it.
Having a locker is a huge convenience too. If we needed sweaters or bought anything, we just rented a locker. So easy! And you can go in and out of it all day.
