We we've been there a couple times this past year. Last October, our youngest was 15 months. I think you'll be able to take an 8 month old on anything that doesn't have a height limit. That would include Small World, Pooh, Peter Pan, Dumbo, Cindy's Merry-go-round, Tomorrow Land Transit Authority, Buzz Light Year, etc. Some of those rides can be dark, but our experience with our 3 kids is that the dark doesn't start to bother them until they get older. Interestingly though, the one ride that bothered our 15 month old was Buzz Light Year....it has lots of flourescent colors. I've talked to other people whose kids absolutely loved that ride because of the colors, but we had the opposite experience.....we even tried it with him a few times because it was our 8 year old's favorite ride.....we were thinking maybe he was just tired the first time, but we got the same reaction later. Anyway, have a great time!
