First off, lemme talk the rumor. If this is true, then GOOD. This is what they should've done since Plaza was finished. I hope to see the Blues Brothers moved to plaza.
About the HoH building, I honestly don't think there's too much space they can use for the attraction. Oh sure, that and the Globe Theater combined would make a descent amount of space for an attraction, butwehn you take into account that there needs to be a queue space AND sace for people to squeeze by, I don't think that's probability. Besides, Uni needs a full-service restaurant and Globe could use a "rent-out space"; not to mention that it is a potential future maze venue for Horror Nights. HHN needs more large-space venues pretty badly.
