point loma university (and the areas around it) is a must see, the little library there was on playboy's top 10 places to do it, but you are with family, so unless you get out to wheel....
Sea world is like a mini disney. 78 admission, gets you a year pass? I wanted to go for 2-4 hours, so we went to the zoo, and took the bus. Saw cool animals, and didn't break a sweat. Saw the cheeta being walked around by a dog (and a ton of handlers).
all beaches are good,
miramar airport if you are a top gun geek,
la jolla horserace track (is that still open?),
