Sure you can find hotel rooms for $150/night, but for moving a family? As I said they're going to be too small or in too rough of a neighborhood. For instance the Extended Stay in San Rafael starts around $120/night after all the taxes and fees. It's also downwind of a sewage treatment plant, right next to 580, and in a fairly industrial area.

At that price point in the city you've got options with, e.g. Travelodge, and you can choose between being right next to the freeway or in the middle of the meth epidemic. For a single occupancy room $150 would potentially get you something comfortable, but for moving a family? Not so much.
