There have been reports that DVD has been internally testing various VGF designs/layouts in a SSR model. It's not open to the public, but the Imagineers.
It's convenient for them to test furniture, patterns, etc there while VGF is being built.
It's easy for DVD to keep the room setup at SSR. When VGF sales start, use the SSR room plus have a room at VGF for people to see. Much like they did with BLT.
