Well they have started building on the HM. Yesterday night they had lights up on the roof and occasionally you would hear the audio. I'm sorry that I do not have pictures but I could not get a decent shot. Anyways at first it appeared that there were decorations on the roof that were similar to the haunted mansion during Christmas. You know when the night before christmas decor is up. I asked a cast member what it was and he kept it brief by saying that he can't release much info on the refurb but that it will include new audio and new "spirits." Other than that everything around thee parks was the same, MGM was very packed.
