LA is the place to be, whatever you want to do there is something for you.
if you like to walk, shop and talk then head to the third street promenade in Santa Monica or City Walk in Universal Studio.
if you like to have fun and please the kid in you, then head to Disney, it is a happy place to matter how old you are.
if you are into culture and the art, then LA got tons of that, from museums and small theaters to events all over town.

Well you kinda have to let us know what kind of things you like to do... so we know what it is you'd consider cool.

forget LA, talk san diego, we r much cooler...
