Only once on a business trip have I had to share a room, a group of about-to-be college graduates was visiting a potential gradual school (that's where you gradually learn you don't want to be in school anymore). My roomate & I opened the door and looked...and looked....and looked at the king sized bed. We called the front desk and fortunately they still had a room with two doubles for us.

Maybe he thought I'd be a snuggle-bunny.
