With the hand full of providers i have been with, they all have stayed at the same up scale hotel.  Im worried that one day i may be spotted by the people who work at the hotel and be questioned by the LE. Im i being plain ol' paranoid? or should i not go back?

i have only been there only 6-7 times.

But if you're in a large city and the hotel has a big, busy lobby it's really unlikely anybody noticed you.  Just try to be unobtrusive and stay as far away as possible from the front desk, conceirge desk and front door.  Is there an upper lobby where you could lurk?  An area near the banquet rooms?  Also, mention your concern to the ladies by e-mail and suggest other hotels.  Just be sure you know that these hotels have hobby-friendly lobbies and you don't need a key-card to access the elevators.
PS:  It's also likely that, if the hotel in question is heavily used by providers, the staff knows about it and turns a blind eye.  Then the main question is, what does local LE know?  So you are right to have some level of concern.

By now you know the hotel layout...  cut you lobby time by 50%.  Do not exit through the lobby.  Walk down the end of the wing stairwells & out the exit door.  Going down the stairs is not too stenuous, even this old fart with a cane can manage it.  Some of these are key card access to get in, but you are going out!  If you need to change wings, do it on an upper floor.   Park nearer the exit door than the main entrance.

My favorite time for seeing escorts is mid-afternoon. At many hotels, however, it's hard to blend in at that time. For that reason, I've often gone with evening hookups.

Also, if you haven't already, you should study up on what to do if you are stopped and questioned. It has helped soothe my paranoid feelings just to know that if I shut the fuck up (STFU), there isn't much cops can do about a misdemeanor they haven't witnessed. TER's Legal Corner board has a lot of good discussions about this.

I'm not in your situation so I don't if I'd start feeling uncomfortable, but here goes.

Some people say, "Don't talk on your cell phone in the lobby as you head to the elevator! They'll know you're there to see a provider!" WHAT? People talk on cell phones in the lobby all the time! "A man with a briefcase, not a suitcase! He can't be guest so he must be a ... CLIENT!" Umm, hotel guests attend business meetings and carry briefcases.

I will sometimes visit a hotel bar, restaurant (well, rarely) or gift shop or lobby (public) bathroom or  ... pay phone ... whatever. Those are public places, not just for quests. What's wrong with stopping off for a drink after work or before a dinner date? (Wrong would be drinking and driving.) No one has ever asked me if I was actually there to see a provider (and most of the time, I'm not!!). Of course, I'd avoid getting too chatty with or confiding in the bartender. (Unless she's really hot!)

Just stop in a few hotels when you are NOT hobbying and look around. It's full of regular people, not a roomful of providers and clients. Stop at the bar, have a drink (and some pretzels), tip the piano player,  and look around at all the normal people ... kind of like you.

Now, if someone starts to recognize me ("Nice to see you again, sir.") or chat me up or makes obvious uninvited conversation on the elevator ("12th floor? A lot of guys are playing poker up there today."), I'd start to get nervous!

Be careful, be alert, but don't be paranoid.
