My favorites are:
1. Pirates of the Caribbean--It's such an amazingly detailed classic and holds so much nostalgia for me.
2. Haunted Mansion--The birthday/ballroom scene always blew me away as a kid. Again, it's in the details.
3. It's a Small World--I just love how much there is too look at. Even if I go on a thousand times, I always find something new.
4. Indiana Jones--I went on this 3 times in one day right after it opened. For those who remember the wait times back then, that says enough. I've never seen so much intricacy in one place. I would love to break down in the drawbridge section just so I could sit there and look around more.
5. Matterhorn--Yes, it hurts. But, it's also a first of its kind and there's something so fun about laughing with all of the people who are shocked by how uncomfortable those last few drops/turns are.
