For the last 5 years, I've switched to using a fanny pack at all theme parks. It has worked SO much better than a backpack...smaller, lighter, easier to access, less bulky, etc. Best of all, you don't have to take it off for rides. Sometimes you have to slide it around to your hip, but that's it...EASY! Just travel lightly & you're good. I just take sunglasses, small camera, money, credit card, ID, my ticket, my day's plan, pain reliever & maybe some hand sanitizer. I've never missed anything I left behind! I've even used it when going to the parks with our two young children (3 & 9 months)...then we need 2 fanny packs...one for me & one for my husband...one has a couple diapers, a ziploc with wipes, ziploc with formula, small bottle, and a ziploc with some snacks. Amazingly, it all fits! Try it!
