Actually it may be very easy to get in. We stayed there this past Sun and Mon night and every time we took the skybridge from the Contemporary, the doors were always open so anyone could come in. Also the attendant in the lobby just checks to see if your room key says DVC Member but doesn't check that you are actually staying in the resort. So unless there is a secret number on the room key that signifies BLT, if a DVC member staying on property gets in through the skybridge, then they may be able to get into TOTW.
