San Diego is a great place to visit. The weather is perfect, cool near the water and hot only a few miles inland. Balboa park has many museums and a zoo. There also is a wild animal park and a winery only about an hour north. Fishing craft, pleasure boats and naval ships all share the bay. All up the coast are many interesting towns to visit. The seafood is great. There is a large marine corps training facitilty and also some navy training facilities.
Disneyland is about 2 hours north of San Diego and a little south of Los Angles. Everyone can have a great time in Disneyland. This is a smaller place than Disneyworld in Florida.
