You can actually tape most rides, as long as you don't use an external light or viewfinder. There are a few that they do not allow you to tape at all. The only one I can think of off of the top of my head is Stitch, but I know that there are a few others. I am taking my camcorder with me in 19 days and can't wait to tape everything, and my kids will love to watch it over and over again when we get home.
