Last night a guest went to the attic alone. He saw the shadow that I saw once. Huge guy, like 300lbs., shadow shaped like a man walking thru the attic.
The guests in #1 said they heard something drop, yet when they searched for the item nothing.
When the entire group was in their separate bedrooms, they all heard loud noises, furniture moving, and footsteps above in the attic.
