Even though I think there are more choices with merit, the OTHER poll has prompted me to create this one.
The choices are based on attractions with showbuildings that have closed since ATIS' final adventure. And voters can make more than one choice.
Tomorrowland Stage (closed 1986)
America Sings (closed 1988)
Mission to Mars (closed 1992)
CircleVision (closed 1997 to make room for the Rocket Rods queue)
In addition, there is a choice for ATIS of course.
There is an option for developing a backstage area or Other unlisted area.
And there is an option to not build Star Tours at all.
