I will be in San Jose Sept 25-27,, then heading to Napa for the 27-28. I have a coworker who said the Courtyard Marriott Vallejo was fine and I also heard its not the best area, would it be better to stay at the one in Fairfield? I'm not to paranoid or concerned but what would be better and closer to Napa?? Also thinking of taking the ferry to Angel Island...is it worth it? Thanks for the info!
