I love the design in of the Tower of Terror as you queue up to go on the ride. I know my Dad would like it, too, but he can't actually ride the ride due to back issues. Does the TofT have an "escape route" from which you can exit before you actually board the ride? Is there a list somewhere of this option for all the WDW thrill rides and if they are easy to use for folks with some mobility issues ? I'm looking for ways Dad can enjoy at least some of the experience with us, rather than waiting outside while we ride. Thanks!
