I've only been walked twice. Once it was at a CY in CLT. When I pulled into the parking lot, I noticed there were only two cars parked. It looked quite odd, like a ghost town, and I was thinking how quiet the room would be that night.
When I walked into the hotel, it was a different story. Loud people jamming every sofa space in the lobby. The desk clerk explained there were busloads of German tourists and they needed more rooms than were reserved. The clerk asked if I would mind staying at another property and gave me the choice of which one. My coworker who was also supposed to stay at the same CY was given the same offer.
My point is the parking lot tells you nothing. (My point is not that German tourists are loud, just these specific German tourists.)
