We are visiting from San Francisco over New Years Eve. We're staying in downtown LA, near Wilshire and Grand. We originally had a dinner reservation at Roy's but we were just invited to a private party at Shutters in Santa Monica on December 31 from 5-8 PM. I understand there is a "Times Square" type New Years celebration scheduled in downtown LA that night. I'm wondering how much traffic we can anticipate going from downtown LA to Santa Monica and back. We would like to attend the party, but don't want to end up in gridlock. We also don't know LA very well. If it's a real problem, maybe we'll skip the party in Santa Monica and stick with Roy's. Any input would be appreciated.
