Anyone know if this would be ok for rides? Specifically Hagrid's, Gringotts and Forbidden Journey. I've been on Forbidden Journey at Universal Hollywood and there isn't a lot of room once the bars are down over you. I'm worried about the thickness of it once I put stuff in it. I'd love to avoid the lockers if I can, but if this won't fit on the rides and I have to do lockers, I'd rather just bring a bigger pack. The dimensions are 7 x 2.8 x 13.8. It has a three prong clasp.
