You don't even need to be a celebrity or a hedge fund to do that.
The public state college I attended rented out Six Flags every fall semester for a day, with free (or nearly free/subsidized) tickets for students.
It was a great way to attend, because it was basically students-only, so no need to worry wasting insane amounts of time in lines. And overall, the vibes were great.
This is an excellent used of student activity funds.
In fact, a lot of colleges have a pool of money for just this kind of activity.
Rutgers used some of this money to organize a paintball trip. On the way back from that trip is how the club got started which then turned into a team etc. I was one of the first officers and that's what led to me working in pro paintball several years later.
