Needing to visit relatives(mom and sister) in San Diego in early December from near Austin, Texas. Trip will be about 14 days total. Unfortunately, they have no place for us to stay, so we are at the mercy of motels(?) and restaurants. For someone on SS, that is not something we are looking forward to, but my mom is 92 and I really need to visit. Wife has a brother that lives in Concord, Ca., so we were looking at maybe going up there for 3-4 days during that time. Anyone have experience recently in making any similar trip? We will be traveling in a 2006 Dodge Caravan, gets about 21 mpg. Any and all suggestions will be appreciated.
