This will be the first time I've visited the parks with a backpack. I'm assuming for many (all?) rides, I can not bring my backpack on the ride. Do they have a designated spot to put your bag when you get on the ride, or do I need to make other arrangements for my backpack when I ride? I'm assuming rides like It's a Small World, you can bring it on the ride, or is that an incorrect assumption? Thanks so much!
