2 weeks, there's a lot of details you can check out with that kind of time. I would plan rides on the slower days (Tuesday/Wednesday), casual strolls around the park on busier days. A day with a Cabana by the pool if this tickles your fancy. Some time in DTD, maybe catch a concert. Also stroll around the hotel areas too, always cool to have a tour.
For offsite activities in the area, beach one day might be good (Huntington or Newport). Medieval Times/Pirates Adventure in Buena Park. Could do Knotts too. For shopping a trip to Brea Mall would be worth it. There's a Melting Pot restaurant (fondue) and Yard House (100 beers) nearby. Other nearby Malls include Block at Orange (Outlets) and Santa Ana Mainplace.
Venturing to LA, checking out El Capitan and Chinese Theater in Hollywood. Daily tours from
Disneyland. Burbank Studios would be worth it too. Maybe do Universal Studios and Citywalk if feeling adventuresome. If you really dig the good life Beverly Hills is there.
For your San Diego trip, be sure to check out Gaslamp district in downtown. SeaWorld too depending on your opinion.
Legoland is another fun place for the kid in everyone.
