I have been to California three times now. The first time we had a couple of days staying in San Diego. The rest of the fortnight was in Anaheim. From there we visited Los Angeles, Hollywood, Santa Monica etc etc.
The next time was in 1997 where we stayed at Anaheim again. Then in 2001 we went there again with my parents and their friends. There are various theme parks besides Disneyland. We went to Knotts Berry Far, Six Flags Magic Mountain, Universal Studios and City Walk.
We also visited the newest park, California Adventure and also Disney Downtown.
