Here's the best I can find, searching 🔎 this forum for "weekend" in the subject title:
Even though the prices are 7 years old, the gentleman provide a rule of thumb that 2 nights should be about 1.5 times the overnight rate, and a full weekend should be about 2 times the overnight rate. Plus, the host pays for his companion's travel, meals, and shared entertainment.
The other topics with "weekend" in the subject title never mentioned rates, but provided good insight on how to make a a weekend hire go smoothly. A key takeaway is providing a few hours each day of personal time, where the escort is free to go out on his own, use the gym, make phone calls, and just be "off the clock" away from the host. Otherwise, the temptation to turn on the phone during time together is too great, and both parties end up uncomfortable.
