I am visiting Center City this week and I am a occasional hobbyist that has nver been to an incall location. All of the outcall meetings I have had (just a few)have been safe and worked out well. I am concerned about visiting someone at another location...any advice? Also, any recomendations for this week?

In my experience, incall is just someone else's hotel room. It works better for locals that can't use their own house / apartment. If you already have a room at a nice hotel, then outcall would work. Hope things go well for you.

If I'm on the road for a business trip I try to do outcall appointments. But when I'm home I much prefer going to a provider's incall location.

As long as it's a well reviewed provider or agency I really wouldn't worry.
