After spending 3 weeks on the East Coast of USA, my wife and I are planning to hire a car and take a leisurely 7 - 10 days to travel from San Diego to Seattle in early March 2014. Is this feasible (or am I dreaming) and what route should I follow? What places should I definitely visit and where would you recommend that I stop and stay? Are there places I should avoid (given that it is winter), should I hire a 4 wheel drive (or is a standard vehicle OK) and is 7 - 10 days enough time? This will be my first hire car/drive experience in the US so I would like it to be memorable for all the right reasons, so any tips or hints would be much appreciated. We are aged 50 plus and are not "thrill-seekers", we like good food and wine and would prefer hotels to "camp sites".
