What ride at WDW have you never been on? What attraction or show have you never seen?
Does not really matter why (you can explain if you want).
Looking at the picture of Dumbo from a Trip report, made me realize I have never been on Dumbo as an adult, only one time as a kid 40 years ago.
I have never seen Fantasmic (never works with our schedule) or been on the Tower of Terror (no one wants to ride it with me), also Alien Swirling Saucers(no one wants to ride with me)
EDIT: Don’t have to include new attractions that have opened since your most recent visit.
Only interested in what you could have ridden but did not.
FWIW, ROTR and MMRR opening after my last visit, which will be exactly one year next week.
