Funny that this got posted right while I have been struggling with this issue myself. My policy has been in flux over the past week while I've been looking for the sweet spot between my preferences and the needs of clients.
Now, granted, I'm not really experienced at the hobby yet, a newbie myself. However, I've been using the interwebs to arrange (non-hobby) escapades for near a decade at this point, so I know a thing or two about anonymous encounters. (Book an appointment with me, I'll tell you about them.) I'm one of the girls who prefers outcalls, for a couple reasons.
-I'm never doing incalls at my apartment. Never. This means hotels only.
-I have a flexible, yet often unpredictable civilian job, so it's just logistically easier for me to schedule a meeting or two at a time, since I would hate to have a few days all lined up, and then have to cancel because my day job got in the way.
-I don't have to worry about filling a schedule in order to make an incall location financially feasible. Again, that could be an issue due to the day job.
-I'm much more comfortable walking away from a difficult/dangerous situation when all I have to do is grab a bag and go. In an incall (even at a hotel), not really the same ease of exit. Hopefully careful screening would eliminate this issue entirely, but one never knows.
-As I said, I've been engaging in anonymous encounters for a while. 90% of the time, I've been meeting partners at their locations. I've honed a sixth sense about people, based on the way they first engage in conversation and how they handle the arrangements. I have had exactly two bad experiences (not in hobby land, but still), and those two were from not listening to my gut instinct. If I ever got a bad feeling from someone, I wouldn't do an outcall, but probably wouldn't be doing an incall with them either.
-If someone is willing to allow me into their private space, I think it tends to say something positive about who that person is.
-I'm not doing this as my primary source of income. So, walking away from a date won't mean not paying the rent. Granted, it might mean having to eat PBJ sandwiches for a week or so, but hey, I'll be safe and secure while eating those PBJs!
-I have a strange voyeur thing about being in other people's houses. I don't know why, but it's always made trysts more fun for me when I feel like I'm being naughty in someone else's space....
Again, I don't mean to be talking out of school here, but it really comes down to the girl and what their motivations/concerns are. And, frankly, the logistics of their situation.
