Interesting. My experience in NYC even with folks in the 20s is they prefer going out BEFORE it gets super late, with the super late nights only happening for shows (where the DJ/main act doesn't come on till 1:30 AM).
I've also anecdotally seen more day parties which might be driven by demand from the former rave crews who are aging out.
