The nearest ice rink, I could walk to in 10 minutes or so, and do so to get my skates done. The rink I typically skate (when healthy) at is a 15-20 minute drive at that time of day (0700 on a Saturday). I happen to live in an area (metro Boston) where you can't swing a cat and not hit a rink. Do they all have adult hockey times? No, but they all absolutely host kids programs.
I would prefer to travel a half hour at most. I have to get there, get dressed, play, get undressed, and get home. For a 9pm session/game, more than that is simply not worth it for me. However, as noted, I have the luxury of many, many rinks in that 30 minute radius.
Before I had a car, I was willing to travel further because the rink had to be transit or foot accessible (with gear). The year I learned to play, it took me nearly 2 hours to get to the rink. Two buses and a half-mile walk. Glad I don't have to do that anymore.
