Disneyland, was crazy packed. It felt like we were all cattle, but we made the most of it and did meet and greets. Had a great time at California Adventure, because it wasn't as bad as Disneyland. Busy days for Disneyland are December 23-Jan 1 and July 4th. I would advice you to avoid those days not worth spending all that money and not being about to get on a ride, because lines are so long. waiting time could be a few hours for 1 ride.
