This idea works for anyone of any musical ability. Marriott partners with a musical equipment manufacturer like Roland or Yamaha. Then in select hotels, perhaps near the exercise facility or lobby, set aside a room, split it up into 4 sound proof mini rooms. The mini rooms (with windows) can be interconnected to each other (via headphones) if people want to jam together, or kept separate if you just want to mess around with an instrument on your own. 4 rooms, drums (everyone loves to smash around on drums), keyboard, guitar, and bass. Perhaps similar to how Guitar Center sets up its lesson rooms... ooooh, there you go, partner with someone like Guitar Center.
