Best to go down the stairs at the far end of the hall and out the exit there, not thru the lobby.  I do this all the time at suburban hotels which are usually 4 floors or less.

Front desk attendants more than likely know what's going on anyway.  They probably have a chuckle watching men come out and knowing he was in for 1, 1.5, 2, or whatever... and how happy/exhausted he looks on the way out.

For that valet to write down a car's tag's number says to me that he is bounty hunter, and that is pretty gruesome to consider.

In any case, that gal (and most likely her pimp/driver are idiots supreme.

She was probably working for one of the local agencies that pre-date review sites and Internet savvy agencies and independents. Review sites and other on-line resources have not only led to higher levels of service, but more sophistication and awareness of privacy and security concerns. Escorts today are very different from the outdated stereotypes that still pervade popular culture and naive news reporting. I know I am assuming "facts not in evidence" here, but I suspect that she is probably not plugged into the online "hobby" culture and will not get any much needed feedback from your post. But, it was certainly worth a try!

Prior to arrival, I usually go to the hotel websites to see pictures of their lobbies and other public areas.  Then, I choose clothing that will blend in with the furniture and decor.  You know what I mean:  

If they have a lot of chandeliers and crystal vases in their lobby, I'll decorate my coat with prisms, glitter and mirrored bling.  That way, I can slink along the walls and they won't even notice me.  I can see THEM looking in my direction, but since they can't see me they (usually) don't say anything.

On another occasion, the website showed that the hotel I was visiting had numerous fountains in their lobby and upper levels.  I donned some work overalls, taped "IMP Plumbing" on my back and emptied my briefcase into a toolbox.  When questioned by desk staff, I said, "Plumber.  I'm here to lay some pipe." and went off to complete my hobby-business.  On my way out, I saluted the desk and said, "Don't worry.  I plugged that leak."

On one occasion, to escape attention entering, I carried a huge potted plant to the elevator.  I knew I wouldn't be able to carry a big plant OUT of the hotel (they'd think I was stealing it, right?), I had packed some oversized "Happy Birthday" mylar balloons and a small cylinder of helium in my briefcase.  They didn't see ME leaving the hotel ... they saw a bouquet of "Happy Birthday" balloons.  

I'm sure glad I think about this ahead of time and can plan in advance.  

The WEIRDEST thing that happened was when I showed up at a hotel in regular business attire to meet a guest in their room and go over some work before a larger meeting.  As I was leaving -- dressed normally mind you -- hotel staff didn't say a thing!!  Somehow, they must have known that I was there for business-business and not hobby-business.  It was scary at first, but then I noticed people using their cell phones in the hotel lobby.  Since only hobbyists do that, I think they must have distracted the hotel workers attention.  Whew.

My chandelier camouflage outfit:

I can't be the only one who stops at hotels when driving distances to use the off-lobby restrooms. Every 3-4+ star hotel has bathrooms off the lobby. They are WAY WAY cleaner than highway rest stops, fast food joints, etc. They are usually right off the highway, pull in, walk into the lobby and there's always a little sign, elevators this way, bathrooms that way. Never have I been stopped by hotel staff. So there are other reasons people come and go in hotel lobbies.

The paranoia of the hobbyist!  Just because you were there for YOUR sexual interests doesn't mean every hottie with a roll of dough is a hooker.  How do you know she wasn't going to bet on the ponies one last time at Suffolk?  Hell four beers at Gillette will run you a roll of 10s.  Let us not forget the stereo type now of what YOU think a provider will where.....
