Agreed. IMO this is the best pass because it gives you a ton of variety and gives you a suprisingly good bang for your buck. Northstar has great parks, Kirkwood has amazing terrain, and Heavenly has that party and is just plain huge. Also, no matter where you are in Tahoe, north/south, you'll be covered.
To get up there, zimride.com is always an option, but there are also many ski bus companies in the bay area (e.g. Bay Area Ski Bus, NAC Ski, Tahoe Snow and Sun, Ski Mela) that do day trips and sometimes even a weekend trip.
If your interested, you should hit up the Snowbomb Ski & Board Fest in SF at AT&T Park to get some more info on all things Tahoe.
