Road trip from Seattle, WA to San Diego, CA

My west coast road trip was so much fun and now my computer is slowly dying because of all the vacation pictures.  My best friend and I took a week to drive from Seattle, WA to San Diego, CA. We rented a car and stayed with friends everywhere except for two nights. Below is a breakdown of our costs in case anyone is interested in making the same trip. All figures are ball park. The numbers will of course vary if you choose to make the same trip depending on time of year, type of vehicle, and where you live. Flights Two round trip tickets to Seattle returning from San Diego:  $700 Rental Car Pick up in Seattle, drop off in sand Diego: $450 Gas Money We had a economy rental, I believe it was a Hyundai Elantra: $250
