How and what does someone do when they "party" for three days?

I’m intentionally not mentioning his name but some professional basketball player possibly with more money than brains supposedly paid $75,000 for 3 days of “partying” with 2 sex workers in a legal Nevada brothel. That got me wondering: What the heck is worth that kind of money and why for so long? What does “partying” mean, anyway?

OK. I get it. He has a lot of money, $30–50M, but still, that is a lot of cash for anyone. Wouldn’t he get more bang for the buck if he spaced it out, say 6 sessions of 12 hours each, a week apart? (Or in my case, 144 – half hour sessions, spaced 2 or 3 days apart?) Am I thinking too much like an engineer?

I enjoy sex. And would gladly jump at the chance to engage in it a few times over the span of a few hours. But after that, it’s just not so important. I’m pleasantly satisfied. I’d really prefer a nap or a nice shower or eat a snack.
This sounds very much like, “Death By Snu-Snu” in an old Futurama episode.

I must lead a sheltered life because, for the life of me, I just don’t get it. Do you?
