I've been to O.C. too many times myself over the years. If you like that general feel though but want more to do overall, try Cape May, NJ. You have great beaches and a nice town with lots to do. Lots of art galleries, stores, etc. The ferry goes across the bay to Lewes, DE. Lewes is a neat little town too but not much going on overall unless you head over to Rehoboth Beach. (another favorite of mine) Rehoboth has a great boardwalk and restaurants. Good luck.
