This is a very good question that will be best answered by Renee.
I can share with you what I know. She is extremely selective in seeing a client in the room. I know her since she started a spa, SL, 7-8 years ago. Not long ago, she told me that she is no longer working in the room. That is shutting the door to me. We are still in good terms and I often go to SL to see other girls. When I bumped into her outside the room, we usually had a long chat.
Donโt know your reasons wanting her service but I think you might find her to be restrictive. Of course, still good fun to have.
$ probably not the key to open the door to see her. You can try your luck by going to the spa at peak time and she may take you if all the girls are busy
Everyone has his own, but I find the new force, her successors are young, and have different great talents. I never get disappointed with her staff.
Good luck
