Favorite thing: There are several casinos North and East San Diego. I've only been in Viejas Casino (not big deal.) If you have a chance, go to Vegas instead. The best at Viejas is the outlet center, very good prices.
When I visited Legoland, California for the first time I was really disappointed. It's basically a place for children to enjoy themselves, though there was nifty little things that might catch just about anybody's attention.... the thing is I just really expected more for what you pay (around $35.00 for adults and $27.00 for children) Considering that both Disneyland and Knott's Berry Farms are within two hours of Legoland, I would not spend that much money again. Both of the other theme parks offer so much more for all ages for the same or less money. But it's one of those things you gotta try at least once!
I felt the park was way over rated. However, if you are a Lego fanatic this park is definitely for you. It includes amazing replicas of many famous buildings. All of these are constructed completely out of Legos. There are miniature cities, all built to a child's height. I found that interesting. Some of the cities included Washington D.C., New York City, San Francisco, and New Orleans. You can take a short boat ride and see some other interesting replicas (Taj Mahal and the Sidney Opera House). The food available was pretty good. However, each location specialized in a certain type of food (pizza, pasta, hot dogs, hamburgers, and barbecue). In order to avoid a long walk, I would recommend that you develop a plan of where you want to eat in the morning. Plan your route around that. If you do not, you may find yourself walking to the other end of the park to eat. The food shops are spread a pretty good distance apart. The park also contains a section set up like a castle. There is a huge play area, a stage with shows, and a couple of rides. Unlike other theme parks, Legoland has fairly reasonable prices on the merchandise in their gift shops. These gift shops are very easy to find, as they are scattered throughout the park. Inside the castle the gift shops tend to keep with the theme. Be cautious, the prices inside the castle are more than that of some of the same merchandise found outside the castle. I am not saying that Legoland was bad, it was a nice day trip. However, in the location it is in, there are too many places nearby to compete with (Disney, Knott's Berry Farm, Universal Studios, Sea World, and many more)
Visit Cardiff by the Sea and enjoy a Lobster dinner and bottle of California Chardonnay while the ocean crashes in below you.
Fondest memory: The weather here is fabulous. The ocean keeps the temp at about 70-80 degrees inland and 60-70 degrees on the coast. The golf couses are spectacular from Torrey Pines to Singing Hills.
Favorite thing: Drive Coastal Highway 1 (along the pacific Coast and slow :-) north of San Diego and visit numerous beautiful cities/towns and Pacific resorts.
