Nap Hotels

Okay,
here's an idea that's been percolating for a year. Nap Hotels. I was in the Hospital District (Brookline) of Boston and realized there is a completely unexploited market for shift workers from students to surgeons who work 12 hours and probably need a nap more than they need a good sandwich.
A nap hotel could be set up a lot like a tanning bed joint, with soft sleepy music piped into small rooms comprised of a twin-sized sleep space with a clothing hook for jackets and ties. People could book naps around the clock, 20-minute minimum to 2-hour max. Wake-up calls and music optional. Nap Hotel. Wouldn't you like to know that your surgeon had a nap before operating?

Just a thought.
