Try to settle everything beforehand & not on the fly - have an idea of what a fair offer is for a Inner Room girl, rent a room (don't go to her house or have her over to yours) - get a burn app so she does not have your real # - don't take valuables w/ you into your room (leave wallet, jewelry, etc, hidden in car) - don't be surprised if she flakes on you and doesn't show (perhaps you can find a decent by the hour motel that you don't have to pay for ahead of time) - if you have a conceal permit take your gun (although rare some crazy bitches will set up a custy).
Not trying to scare you, just covering all the possible bases - sorta like giving someone all possible safety tips for driving but doesn't mean death by car accident is eminent.
Inner Room is a bit of a dive so I'd say $150 should do it, maybe $200 max if she's one of the hotter girls - I live in Miami but hit IR 2 or 3x per year and did OTC w/ a dayshift dancer after her shift - I was already staying overnight at the nearby Motel6 and that is where we went - it all went smooth as butter and she was a cool chick willing to please (seemed to wanna fuck as much or more than I did and we went at it for a good hour, I was def spent) - IR not having VIP means a good # of girls are up for OTC & a fair # of custies partake.
