My other tip is to try some of the outdoor rides first like Dumbo, Casey Jr., teacups, etc. If your kids aren't used to going on rides then the indoor "dark" rides can be scary and you wouldn't want their first experience to be scary or you might not convice them to go on any other rides the rest of your trip!

After the outdoor rides, the first dark ride I would recommend is IASW since it's colorful and fun and not at all scary.
