I'm planning to take a road trip from the San Fran area to San Diego next month. Any advice from San Diegans about where I might be able to charge my car when I'm there? I'm going to ask a few hotels if they'll let me charge if I stay there, but other advice is welcome. Ideally, I think we'll want to stay near Point Loma or Ocean Beach but we might end up near La Jolla if that works out better for some reason. thanks all!
