DD is going to Orlando on a school trip. We always do Disney (SeaWorld once) and I love the fact that I can take my backpack on any ride. I'm concerned that she won't be able to keep her things with her at all times. She is a small girl. If she carries a small cross-body purse (big enough to hold her phone and some money) can she take it on the rides with her? She could put it behind her back or even under her shirt/jacket if she needs to. I know that when we went to SeaWorld I had to put my bag in a locker for some rides and I don't want her to have to do that. She will be going to US, Aquatica, and MK.
