Grownup birthday party ideas

I have a February birthday. I have $500 to spend on a birthday party for myself. Want to do something playful (I promise I don’t mean group sex) with like 5-10 friends.

Last year did axe throwing. That was fun. Prev year rented a hot tub w some friends. Also good. I am considering top golf, bowling, bringing some games and food to a brewery. Night time tubing at buck hill.

But I also want to hear Reddit’s thoughts. What kind of silly fun can a pretty straight laced group of folks get into? Can be weekend or weeknight.
