I will be going to Disney in November for the first time. I need to find a suitable bag to carry all the necessities around in the park. I was thinking more along the lines of a small backpack. I will probably only be toting my own items, however there will be children in the group, so I may end up carrying a little extra. I do not want something that will "weigh me down". I also have heard that backpacks/bags cannot be taken on the rides...need to know when considering the type of closure the bag may have. I'd appreciate any suggestions from experienced Disney visitors. Thanks.
