What to do with visitors?

I'm trying to make a list of things to do with the friends and family that will be visiting San Diego in the next couple weeks. I'll start it off - and I would love it if everyone that has more input please comment and give me some other ideas:

• Shelter Island


• Harbor Island


• Little Italy (Gelatto Vero, Fillipi's)


• Old Town


• Coronado (The Del, Moo Time)


• Seaport Village


• Presidio


• Cabrillo/Pt. Loma lighthouse


• Gaslamp (Ghirardehlli's, St. James Hotel roof, Cafe Bossom, Hard Rock Cafe, Horton Plaza)


• Julian day trip


• La Jolla Cove/seal beach


• Ocean Beach (The Black, OB Pier, Farmer's Market)


• Pacific Beach


• Mission Beach


• SeaWorld


• SD Zoo


• Wild Animal Park
