Hi Barry,
Great question...and honestly, one a lot of thoughtful gentlemen don’t ask often enough.
It really is respective to each individual provider. I’d recommend making a short list of the women you’re hoping to meet and checking their websites first. Many of us include booking timelines or preferences there.
Keep in mind that not every provider does this as a full-time career. Or if it is their full-time career, they usually have other responsibilities such as children or they may be touring-heavy providers. Therefore, some may need more lead-up time (two to four weeks) to plan around their schedules, while others may be more flexible. There are also companions who are low-volume &/or in particularly high demand, and that affects availability as well.
And to address the deposit comment an individual posted, every provider’s deposit policy matters. If a provider requires a deposit, a booking typically isn't confirmed until the deposit is received. Some do provide some "grace periods" or 48 hours or so. However, sometimes clients lose their spot simply because payment wasn’t remitted promptly. It’s not personal... it’s just part of the business side of what is, by nature, a very personal industry.
So I’d say: do your research, respect each provider's process, and plan early if you can. The anticipation is half the fun anyway. 😉
Safe travels and welcome to Minneapolis (more often),
Paige
