I just came back from my first visit to Disney's California Adventure. While I will agree with the other posters about it being quite a bit smaller than Disney, I still feel it was well worth the money. My favorite ride by far was Soaring over California. (Ask to be put in the front row, for the best seats.) This ride is designed so well, that you actually feel like you are flying through the air. You can even feel and smell the sea breeze as you coast over the ocean. Amazing! I also thoroughly enjoyed the roller coaster on the boardwalk. I suggest the Park Hopper tickets to save you some money, plus you can spend the day as DCA and head over to Disneyland for the parade at night. One full day at DCA is just about perfect.
