I've had a few 'hotel experiences' but unlike the other posters I was the hotel employee.
Years ago I worked as a night manager in a 4 star hotel used mainly by businesses & executives and during those quiet hours of the night shenanigans did occasionally occur.
One night a handsome guy of about 40 checked in @ midnight & half an hour later rang down to say the light bulb above the bed had blown & asked if it could be replaced. I fetched a bulb from the stores & knocked on his door & heard 'Come in.' I used my pass key & found him sitting up in bed naked from the waist up with damp hair, obviously just out of the shower. After exchanging pleasantries I leaned over him to replace the bulb & found it was not blown but only loose & came back on when I tightened it. I suspect that he'd deliberately loosened it as when I looked down he had pushed down the bed linen & was completely naked with a throbbing boner & a huge grin on his face!
Needless to say that guest got the deluxe room service treatment and when I left, wiping the man juice from my lips , it was me who who had the grin on his face now!
There were othe 'events' that happened during my time there & I'll recount them later.
