Problem is that all the hotel costs will add up, need to find furs in the area who can accomodate us :P. I was thinking of arriving in San Francisco on Wed 18th Jan and either get a connecting flight to San Jose or drive down (depending on company) and check into the con hotel. Do the con thing until Tuesday, check out and go back to San Francisco. Maybe stay there for 2 nights to take in the place (go to Alcatraz and stuff!) and on the Thursday travel down to LA (either by car or train, pending on company). Probably want to spend at least 4 nights in LA as I know I want at least one day at Six Flags Magic Mountain being the theme park / roller coaster lover that I am and then maybe fly back on the Monday from LA.

Fortunately, if I booked today for example, the flights from Heathrow to San Francisco on 18th and return from Los Angeles on the 30th currently come to £210 which is a very good price :).
