Lots of cool video and pins. I stay up until they close, 2 AM on Saturday. Easiest way to get on a machine.
Cool things to look for:
Since you have seen limited pins all the "A" titles that interest you, and rare titles that you will never see in the wild. The lines are not long, especially at odd hours. Most of the long lines are on the newest Stern machines. Last year it was Tron, the year before that Iron Man.
Rare games: Big Bang Bar, Kingpin, Addams Family that has to be pedaled to run, and Whirlwind with an industrial blower really gives you a wedgy.
The cool vids. The Act is a Dragon's Lair type cartoon game, which is fun.
My favorite, that my buddies and I play late at night after having a couple brews, is Warlord cocktail. Ultimate Co-op game.
California Extreme is my favorite show as it has the best of both worlds and is at a hotel. As for your parking/driving problem they have a big garage there and I have never seen it close to filling up all the years I have gone. Once again time of day is important, but I really do not see any problem just parking your car there. (Can't remember if there is a small parking fee-)
