I was at IOA back in 2002 and was exiting Spiderman, when a TM came to us and told us not to leave the giftshop cause there was a Tornado Warning, and the a Tornado was spotted in the area. There must've been at least 150 of us in the shop. The park then lost power for a good hour or so.
When the warning was over, everyone exited all the rides, shops, and restaurants. A whole lot of mayhem.
I don't think the Sindbad Building is big enough to house that ride. Unless they gut it completely and add-on to the show building by taking up the space in the employee parking lot.
Which is what I think might happen. I mean..it sounds logical enough.
