As much as I hate my newbieness to show I'd like some info from the seasoned guys on how to call an escort in Rio, other than the obvious.

I'll be staying at the Princess Copa.

Would I call, then meet the girl in the lobby? Would I call and give her the room number?
Would I call the front desk and say to expect her?

Thanks in advance.

Just call and give the agency your hotel name and room number. At the Princess, you can wait in the lobby (not the best choice since you don't know exactly when she will arrive) or just wait until reception calls you. Remember, though, that you and your guest will need to fill out a "guest" form and she will need to leave her ID at the desk (don't worry, most of the girls know the procedure).

If you wait for her in the lobby, you can sign the form when she arrives. Since I found that a little uncomfortable, once I found out when she was going to arrive, I went downstairs beforehand, informed the front desk that I was expecting a guest and pre-signed the form. This way, when the girl arrived, they just escorted her up. The other option is inform the front desk that you have a guest coming and ask them to bring the form for you to sign when they escort the girl up to your room.

I personally found Karla Models pretty good. Ask for the girl to bring the book. Most of the girls had nice bodies, but not all of them had great faces (although more than a few did).

At the Rio Rioss, I just called the escort agency, gave them my hotel and room number, and of course, they would call my room back in 5 minutes to confirm that I was really there, and then the garota would show up at the lobby within the hour. At that point, the reception desk would call me to ask if I had asked for delivery, I would tell them yes, and within 5 minutes the garota would be at my door. A very good system, I must say.

Karla Models was very good.
