Haunted Mansion at the Magic Kingdom: This classic attraction is well done and I am looking forward to the upgrades in the hitchhiking ghosts.
Pirates of the Caribbean at Magic Kingdom: Another classic attraction not to miss. One of my favorite parts is Davy Jones and "Dead men tell no tales".
Mission Space at Epcot, Orange Version: Very realistic love the feeling at take off. Not for those prone to motion sickness. The only ride at Walt Disney World to have motion sickness bags in it. Also do not eat a big meal before this ride "your stomach might not like you" after the ride if you do.
