Sometime in August the GF and I want to take a little weekend trip (friday to monday) to LA and the surrounding area. We want to go to the beach, walk around and just have a good/relaxing time. We will have a car but would need to find a hotel. I've never been to the LA area so I'm not really sure where the good tourist type places are and what cool stuff there is to see. How is Long Beach or Santa Monica?
