Kane,
You can peruse the “Scheduled Ladies” page of Courtesans coming soon to inform you which Ladies will be there on a specific date. However, this is updated constantly to accommodate last minutes changes so check it just before your trip. http://www.sherisranch.com/comingsoon.aspx
Also, there is a “Weekly Lineup” of Courtesans currently at the ranch. http://www.sherisranch.com/lineup.aspx
I know you’ll have a great birthday celebration at Sheri’s Ranch no matter which Lady you choose. Also, your method of transportation is not critical so use whatever means you must to arrive at Sheri’s Ranch. Also, there’s another post concerning Limos on the following thread. http://newblog.sherisranch.com/forums/topic/general-question/#post-4761
