Since I don't travel on biz anymore I tried to get Annie Rivieccio, who I never sessioned with before, to fly to see me for a day or overnight trip a few years ago. It would be a short flight to my town. She appreciated the invite, thought about it, but declined saying she would have come if my town had more fbb fans and not just a solo long session (or two) with me. Eventually she didn't tour anymore from what I remember.
A couple of years ago I contacted one of my favorites in Florida, who used to be on tour a lot but now has a vanilla career. Still buff, she was / is still doing cam sessions. We discussed it, a Friday afternoon to Sunday AM thing with me getting a couple of long sessions; her being able to see clients in my major city (no longer in the same town I was when I contacted Annie); I pay for the airfare (going to use frequent flier miles), hotel; we'd have lunch or breakfast; and I'd drive her to the hotel and back to the airport. The cash for the sessions was reasonable. But the timing and logistics didn't work. She got busy in her vanilla career and she declined. It seems a lot easier to go see them, in my experience.
