I'm planning a 3 to 4 week road trip from Seattle to San Diego in the beginning of May. I consider to ship my car from NY where I live to Seattle and back to NY from San Diego. I'm wondering if transporting is not a big hassle + cheaper than renting a car in Seattle (which has to be returned in San Diego). Has anyone experience with transporting his vehicle or is it just easier (and just as expensive) to rent a car for 4 weeks??
