I agree with the others that you don't need a car given the bus, the flat roads, and the fact there is little parking at the mountain itself. I would add that a lot of the hotels run a shuttle for skiers from town to the mountain. We usually stay at the rustic inn (just there over MLK), in addition to the included 4x daily shuttle to the mountain they will pick you up and drop you up at the airport for free. Good free breakfast also. The START bus is ok, but can get crowded and you likely will be standing for the 15 minute trip, it also costs a few bucks a day. If the rustic is too much for you check out the 49er, no airport shuttle but decent enough rooms, free breakfast, and a dedicated ski shuttle.
