Yeah, I was wondering what the double room layout might entail when i saw it. With how it's split and how it looks, I would think that maybe
A. Maybe it's going to be a double drive through "show building" so that either more than one tram can experience the attraction if need be or one "side" can be open when the other is down? Probably not, considering they're attached.
B. There's two parts to the attraction. I really hope this is the case! That would be so awesome.
I don't think the first room is a standby room though, as it's too big to be just a standby room, the two different parts of the building are almost equal in size it seems.
