How to spend $4,000 in the San Diego area? -

What activities are there to do besides shop?How can I spend it within one week?

You could do a lot in San Diego with that money!!! If it were me I would start hitting those night clubs and you cant forget that San Diego borders Mexico so you could cross the border and hit the clubs in Rosarito B.C. Mexico they got real good clubs down there right beside the beach. You could do some sailing in San Diego aswell.
