<font color=navy>There is so much to do here in Southern California. Are you looking for another amusement park? There's Knotts Berry Farm (20 min from DL), 6 Flags Magic Mountain (about an hour away), San Diego Wild Animal Park, the zoos in Los Angeles & San Diego.
There are museums & such ... Natural Museum of History & next to it the Science Museum & IMAX theater, there is the La Brea Tarpits, Griffith Park Observatory, Ghetty Center, and other museums. There is the San Juan Capistrano Mission.
There are the beaches, but I don't know with this weather - pretty overcast during the day...
I think it depends on what kind of day you're looking to have.
