To piggyback on what ash_chan said, pretty much the whole point of Fanime housing is to give convention attendees the best rates possible for the closest hotels. They book the most convenient hotels within walking distance and negotiate with them to provide people with cheaper prices. There are other cheap hotels in the downtown San Jose area, but they pretty much require you to drive to and fro between the room and convention center, and they might not be in the safest neighborhoods. So, if you don't want to book through Fanime housing (which is pretty much all booked up except the DoubleTree at this point), you're not really left with any options as far as cheap, walking-distance rooms go =(. If anyone wants to do a search and prove me wrong then go for it, but far as I know, it's either Fanime housing, or something within driving distance.
