I've been to Passive Arts several times over the last five years and have found the staff professional and courteous, and the facility clean and well equipped. I find helpful to e-mail the girl a few days before scheduling a session, to make an introduction and verify she and I enjoy the same kinds of activities. PA is easy to find, and parking is not a problem (I always park on the side of the building). I shower an hour or two before the session (the cleaner you are the closer your lady will get), make it a point to arrive on time (not early), and call to notify if I'm running late.
A receptionist will buzz you in at the front door. If your girl is running a little behind (pun not intended) you'll wait in the lounge, where you can watch a little TV or munch on some candy. Once she's ready your lady will take you into a room to get a feel for what you're looking for, which is a good time to bring up your prior e-mail correspondence with her and give a specific recounting of what it is you like. If the two of you are comfortable with proceeding with a session, she'll walk you back to the receptionist, who will take your donation for the session. I find that one hour is best for a first session, neither too long nor, more importantly, too short--time does indeed fly when you're having fun! You can get a tour of the facility at this point, a good idea on a first visit as the reality of the place cannot be captured on a web site. You can also select "accoutrements" (feather dusters, cuffs, warburt (sp?) wheels, etc.) from a well-stocked room next to the reception area. Then, back to your room for some fun!
Tipping is optional, but I make it a point to tip if the service was good (it almost always is). Your lady will then escort you to the door where you'll say your goodbyes.
