A couple years ago I worked briefly at a local bed and breakfast. The Inn was an old mansion from back around the time the town was first settled. The place was of course creepy just in that it was so old, and had too many little nooks and corners. There were the old passageways for the maids to get to the rooms without going through the main halls, but I was never brave enough to go down them - the cellar was enough of a stretch for me.
While I worked there I was dating the manager, and one night we decided to stay at the Inn. We had few guests at any time, and on this night the place was empty. There was a reservation in place, but they hadn't shown up yet to claim their room by the time we retired for the night, so we just left a note on the door telling them where their room was. We stayed in Room 2, which was on the second floor at the end of the hallway, across from the Bachelor Suite. A couple of the rooms were named suites as they were especially ornate and larger than the regular rooms. The Bachelor Suite hadn't been rented out yet while I had been there as it had been undergoing some renovations that were basically done by this point.
We went to bed probably a bit after 11 but woke up within a couple hours to what sounded like at least two people coming down the hall with their luggage (our door was closed of course). We both sat up a little and listened to them pause outside the Bachelor Suite and open the door and go in. Once things had quieted down and it seemed that the guests were settled in and all was well we went back to sleep, not wanting to disturb them after their trip and late arrival.
The next morning we got up early to prepare the breakfast only to find everything as we had left it downstairs and no guests to feed, nor any trace that anyone had ever been in that room at all.
Thanks!
