Arguably one of the most beautiful spots in California. "The Shores" is perfect. And aside from Del Mar, Carlsbad, and Leucadia, it opitizmizes the best of San Diego County. La Jolla (IMHO) is the best part of San Diego.
Here's some places that are perfect for yourself and your family.
1. La Jolla Cove. Its right up the street from where your at. Just ask around.
2. Downtown La Jolla
3. Pacific Beach and Garnet Ave. ( Look up "Da Kine's". Its great afordable hawiian food right near the beach)
4. Shoreline Drive and Mission Beach (try the roller coaster)
5. Downtown San Diego and 5th Ave. The Gaslamp District
6. Legoland
7. Oldtown SD (right at the I-8 and - I-5 interchange)
8. Fashion Valley Mall (outdoors. great eyecandy if you wear your shades. and your daughters will dig the place)
9. World famous Torrey Pines Gollf Course (if your interested)
10. BBQ'ing at Crown Point. Grills are provided at the park.
Hope this helps.
