We leave for a 2 week vacation in Disneyworld/Universal in 9 days. I recently bought a backpack to carry various items (camcorder, snacks, pancho etc) around the park for my wife and I. My biggest question is what rides will I be able to actually take my backpack on? I realize that rides such as Peter Pans Flight, Haunted Mansion etc will be no problem but what about rides such as Rockin Rollercoaster, Dinosaur, Star Tours etc? I know that there are lockers beside the rides but if I am able to take them on then I would much rather do that then shove it into a hot locker for an hour. Thanks for the help! I'm READY TO GO!!!!
