MEXICO
If you're not sure of the level of interest your co-workers have, start with the more mainstream clubs. Amnesia (south end of Revolucion), Penthouse, Bolero, for example. Depending on their reaction there, you can gauge how they might react to some of the other action that's available.
If they're adventurous enough to visit the Zona Norte for something more racy but you don't want to to take them to the full-time whore bars (e.g., Adelita Bar), then try Hong Kong (on Callejon Coahuila) for an American-style strip club experience with more action available in the private areas. I've also seen some great strip dancing at New York Bar (on Calle Coahuila) on my past few trips, so that could be good if you like lots of young, small-breasted (no implants) women with good stage skills.
Sorry that I can't speak to your concerns about bringing girls to the Camino Real. I always get my hotel room at the Rizo de Oro in Zona Norte, which obviously has no problems with it. 
(Dozens of girls that work in that neighborhood have rooms there already... )
And it sounds like you don't have a wealth of experience in TJ, so I would absolutely recommend that you take taxis to and from these places, unless you've got more familiarity with the lay of the land than you're letting on.
Happy to help.
The Rizo de Oro is a very basic Zona Norte hotel. The rooms basically have one or two beds, a TV, a chair, and a bathroom. They give you a couple of towels, soap, shampoo, and toilet paper. It's pretty spartan, but I haven't had a problem with cleanliness. The main attraction is being able to take girls up to the room without hassle.
My Spanish wasn't great when I started coming here; the desk staff certainly know enough to handle room rentals in English, and a couple of the guys speak it pretty well. Rooms here are $30 for a single, and $45 for a double, with a $5 key deposit. I've never made a reservation, and I don't expect they get any.
Another suggestion I have to add is that there's a new bar called Cantina de Pancho that just added a sports bar and strip stage in a new section this weekend. The manager, Mario, is a great guy, and we've been going since it was just a karaoke bar where numerous working girls from the neighborhood would go to hang out. (Nice to be able to buy a girl a drink and have it not be $7!) It's just east of the corner of Coahuila and Constitucion, and I think it's got really good potential. Plus, my photography will be on the walls in the next few days.
Good point; I think the Internet escorts would probably *not* be eager to go there, although girls that already work in the area should be fine with it. Matter of fact, a fair number of the girls who work at Tropical Bar (right downstairs) live in the RdO, and my friend and I had a couple come to our room after work at no charge a couple weekends ago.
Yeah, we lucked out in that it was their last night of two weeks working in town, and we had showed them a good time without being grabby and pervy with them. So they decided to repay the favor, and told us they wanted to spend their last night with the nicest guys they had met their whole trip.
