4. I can abolutely recommend the following:- San Diego Zoo (full day)- Whale Watching (half day)- Coronado Island (half a day)- Point Loma (half a day)- Restaurant: Point Loma Seefoods (just across the street, voted best restaurant in San Diego)- Drinks: Yardhouse (300 different draft beers to choose from)In the summer I`d imagine the beach area north of the city (Mission Beach, Pacific Beach, La Jolla) will be great too.
