I use to have a membership to the president's club for CAL, and I gotta tell ya, it was definitely worth it, particularly for commuters as not only is it a great place to relax, but the majority of them have a shower facility as well. Also it's great when you're non-reving, it certainly came in handy a few times. There's a uniform restriction, so all you have to do is have a shirt or two you can change into and you're set.

I didn't renew mine, I don't commute, and ended up using the $400 for something else, but I do know a few guys that commute that take full advantage of it.
