Actually, it belonged to Paris first. When
Disney Dreams! premiered in 2012, a control booth with a similar design appeared on the west side of the Central Plaza. Both structures feature similar roofs (and grillwork) but for Hong Kong, the walls were redesigned to feature garden stonework. Paris definitely got a better paint job than Hong Kong's, and a more discreet one at that.
It's also bizarre that Hong Kong required two booths whereas Paris only needed one. I know it's for the projectors (
as previously posted), but couldn't they have gone for the traditional freestanding projection towers that Anaheim uses (not sure about Florida and Tokyo's extended turrets if they function as projection towers as well)? I imagine there would be room for such a tower at least on the sides of the new (terraced?) seating area.
