This is the part he's talking about:
"The only negative thing (very minor) was when I walked into the hotel lobby the lady at the front desk asked me some details. I had to give her the room number for who I was visiting. I think that was weird and told Harley that when I saw her. I don't think she will be using that hotel again."

Best suggestion I've seen for situations like this. First, carry a laptop bag, which makes it look like you're there on some kind of geek mission. If asked your business, pleasantly reply that you're "tending to some personal business." (Which is true.)

Sometimes, I feel even more vulnerable passing through a small, uncrowded lobby than visiting a room where the door opens directly out to the parking lot.
