I only attended one conference in SF, VMworld. We were a vendor. We stayed at a really nice hotel ~15 minutes walking distance from Moscone (picked by our sales VP, I'd never pay that much for a hotel ;) ). I had a good experience. There's no shortage of places to eat or sit around there as well. SF does have fairly reasonable transit as well. This was a pretty long time ago though.
