I could see that being for a bachelor party...women aren't going to spend that kind of money on partying...
At least a couple hundred of it is going strictly toward partying. I'd consider that no problem if I weren't already paying over $1,000 just to fly and sleep there. And she probably isn't going to want to eat anywhere particularly affordable. I spent a few hundred on my best friend's bachelorette party in November, but we stayed in Tampa for it. And I spent a few hundred on one in Miami a couple weeks ago.
My PM inbox is now accepting applications for a sugar daddy who'd like to take care of me through the next few months until this is over, because I'm not wasting my own money on that bullshit.
