Who's been sleeping in my bed?

On Monday my husband and I had to go away overnight.  Since he was at work, I was the one who got to check in to the hotel.  After getting the keys, and dragging the suitcases up to the elevator I finally found our room.  I walked in and stopped, something didn't look quite right.  There was a cup on the sink, so I said Hello?
Nothing, so I walked a little bit farther, the bathroom door was open, the light was on, and a towel was on the floor.  I started to get nervous, and walked into the next room, the bed had been slept in -thankfully no one was in it!  I called the front desk, and then I had to drag my stuff all the way back down stairs and get a new room~ thankfully this time it was a clean room and no one was in my bed!  I felt a little like Goldilocks and the Three Bears!
