Its probably many of you who have done this trip before and there are probably many threads for trips. But i am still asking for tips and places to stop.. Our plan is to travel from San Fran to San Diego with a rental car and the reservation has already been made. This is because we are flying into San Fran and out of San Diego. We have 18 days and here are some of the places we would like to see. Highway 1, Las Vegas, Grand Canyon, some wine tasting (visiting wineries) and Hollywood. We have not been to the U.S before. So my question is, where should we drive and stop. Is it possible to do both highway1 and las vegas, grand canyon.. any pointers.. please help!
