Using the hotel example, who is going to want to walk outside in their complimentary shower robe at 1 in the morning, to plug their car in when the other guy finishes? Will the other guy be awake to unlock the charger? I think charge stations at hotels and motels should be configured to allow a full charge overnight, and thus allow the driver to leave his car in the stall while he sleeps. Playing musical chairs at 1 in the morning doesn't work for me!
