I usually do nooners and it's where I work.

I live and work in the suburbs so I'm always happy to see providers visiting KoP and Ply Mtg. A Center City appt requires more time and planning for me, so is not as convenient.

i'm a suburbs guy.  Getting in an out of center city is time consuming.  I'd have to take 4 hours for a 1 hour appt.  

Definitely suburbs.  Coning from southwest of Philly, I've missed major portions of dates due to traffic getting into Center City.  Besides that, parking is a pain and expensive.  KOP, PM are better, and the airport area is best - easy to get to, free parking usually.  But I understand the ladies like Center City becuz they can walk to restaurants more easily.  So, just find a major chain hotel that has a decent restaurant included!  

I am curious if there is a demand for Incall on the Mainline.

I stay downtown (I’m a regular visitor to the city) and other than uber/lyft have no means of transport to the ‘burbs. So downtown providers or those willing to come downtown get my attention.

I live in Lehigh Valley and would love to make a connection in the area in lieu of traveling to Philly.   It seems the availability see sparse in this area.    
I think the ladies would be successful and have less competition if available in this area.
