Beat LA,
The Sheri’s Ranch bar is open from 11 am to 3 am, but you may arrive at anytime since there is always staff on duty. It’s best to visit the Courtesans between those hours too although not imperative, because the Ladies frequent the bar during business hours. Furthermore, no prior appointment is necessary.
You should allow approximately 2.5 hours for the 120 mile round trip drive. In addition, you should budget another 2.5 hours to select a Courtesan, become acquainted and then party. You’re looking at 5 hours minimum to avoid being rushed.
