As long as their name is on the reservation there should not be a problem, but they would probably have to give your name also and room number. We were there Christmas week and our son's friend who is local was going to stop over one evening to visit us. I asked the front desk if there would be an issue with him coming thru and parking for a few hours. We were told to just have him tell the security person in the booth that he was visiting such and such family in room number whatever. He had no problem whatsoever, and this was the busy Christmas week. I admit I was a little surprised...I figured they would make him valet the car at the Contemporary.....although there was still plenty of parking at BLT even during this busy time, although most open spots were closer to the tennis courts than the lobby. Enjoy your stay....we love it there. Oh...if they want to go in and out of the parking lot it would be easier if they had a magic band....the back up at the booth can get crazy.
