Planning for my first solo trip to USA West Coast but I can't decide whether to visit in mid June or September? Also I am not sure how many days I should spend in each city, San Francisco, Las Vegas, Los Angeles, San Diego, Santa Berbara. Since I am traveling alone, I would rather to spend on budget. I would like your two cents view and travel trips so that I can enjoy my solo trip to the fullest. By the way I wish to spend 14 nights in West Coast. Any suggestion or recommendation is welcome and appreciated. Thank you.
