I've been looking to book the Lightning Lane/Premier Pass for our upcoming Disney trip and for the day we have reserved at MK, I can't help but notice 99% of the rides are designated any height, any age and slow. Tron & the Seven Dwarfs are "unavailable". Our kids are at that age when The Magic Carpets of Aladdin doesn't cut it. I was hoping for a way to slice some of the wait time from Tron but no such luck. How else can we book Tron or Space Mountain? Isn't there a day-off wait list? I need to look into that.
