Thank you everyone for your help.

I found the best rate at the Hyatt ($79/nt), and it also helps with the Gold Passport promo. It would be more convenient to fly to Orange County, but I am flying BOS-LAX for $109 (thank you Mizzouflyer). For convenience, I will rent a car. I hope the traffic isn't too bad. It probably can't be much worse than the Big Dig traffic.
