Hi, This has probably been asked a ton of times before, but I'll be in San Diego for the day next week and would love to check out the beach for the few hours that I have before my flight back. I'm driving down with a friend who is moving and she has to continue on, but I'm flying out from San Diego. I will not have a car, and I understand that downtown is close to the airport. How should I kill 5 hours or so, wanting to soak up the sun? And how do I get to the airport on my own?
