Very low likelihood of success
[QUOTE=RumDude;6509637]Coming into your fair city for work. One night only. Would appreciate a solid sure thing that would outcall to my hotel. Nice one downtown. Preferably white, spinner type but athletic fine too. Under 40. I can reciprocate with intel in Texas, ok Missouri Virginia.[/QUOTE]I would say your best bet would be to just go to one of the many fine AMP's this city has to offer. Many should be walking distance to a "nice downtown hotel". Some of them might even have some white ones. Most are Asian. Some are black.
Most escorts (or any sex workers) in philly are severe drug addicts so they are not likely to be athletic and are not dependable to keep an appointment. The only exception would be the hundreds of Asian massage parlor workers who come in, make money, and leave.
I'm sure there are women out there who would fit your description and are willing to exchange goods for services, but people on this site would not likely just give that info willingly and the girl would not want to see someone new and unvetted.
Philly has many great AMPs that are around the 200 mark in the Chinatown area. You just walk in, pay your fee and bone some chick and leave. No fuss.
I've heard some good things about sugar babies but I don't have much experience with that and I imagine it would take a lot more effort and money.
If you have the time and energy to dig through the trash, you can try to test your luck with finding a decent one off the street but there are lots of risks with that. But if you are luck at finding a fuckable one, she'd likely be willing to go to your outcall for a few hundos + buying some drugs to keep her high during the whole process.
