I will never again ride Mission Space -Orange. Have ridden green mode, but DH and kids just have to do without a navigator if they choose orange.
DD will never do Stitch again. She was 6 when we did this and DH and I had talked it up based on our previous experience with Alien (which we both really enjoyed). DD was FURIOUS for the rest of the trip that Stitch burped in her face.

She also would not do it the following 2 trips, Stitch is on her bad side for life apparently.
DH will never ride Carousal of Progress, he experienced it with his parents as a teenager. I finally got to see it with my Mom and Grandmother and DD. DS would not even try it after DH's disparaging comment, and enticement to ride a different ride with him.
DS will probably never ride Ellen's Universe again. He has humored us on the other trips but after this last one he declared that he will never be tricked, cajoled or guilted into riding it again.

As a family we have experienced all current attractions with the exception of the the
Liberty Belle, DH has managed to hide the boat from me every time

(well he got lucky the first trip b/c it was being serviced). I fully intend to ride this as a family on some future trip.
