Green Rooms and the No-Lose Key System
While traveling in Europe, I encountered an amazing, "green" system that is earth friendly and prevents you from losing your key in the room. After unlocking your room door, you place your key in a wall slot near the door that operates the heating/air conditioning system. This conserves energy by not heating/cooling a room you've vacated for the day. This idea can also reduce costs for the hotels, helping keep costs lower for guests.
