Hey guys. I' ll be heading to San Diego on Dec 6th for a week. My daughter just had a kidney transplant and was selected for a Make-A-Wish trip and she wanted to check out the zoo / safari / Sea World. I am heading there with my wife and teenage son and daughter and we will have a couple of free days to kill. Didnt know if some of you guys may have some suggestions on things to see/do while in the area. We're pretty much open minded to anything family oriented, so obviously an escapade to Tijuana is out. We've been to Northern Cal and LA , but never to the San Diego area so we' re going in blind. Any suggestions? Things that must be seen, places to explore, places to avoid , etc.
