As for the current Stage: it works for DAWM and the arches has strobes which work in DAWM and Wishes so, there's that. However, it would be nice if more people could fit on the stage..If that's the reason CTS doesn't have it's winter number anymore. I know CTS had it on the CSC Stage. Never saw CTS on the 90's Stage.
Interesting that MK has had their biggest shows with just one Staircase right in the middle of the stage: Tencentennial, early July 4th shows, Christmas Spectaculars. Although they made America The Musical a good size(bigger on July 4th)on the 90's stage.
