We spent two days at Disneyland with a park hopper ticket so we could come and go as we pleased between Disneyland and California Adventure Park. I liked this arrangement as when we got tired of one park we could walk to the other. We stayed at the Candy Cane Inn (awesome). It was walking distance from the park so we were able to arrive when the park opened. I highly recommend staying close by, as we did not not find the crowds bad at all in the morning, quite pleasant. We were able to go on any ride we wanted without a fast pass, some we were able to walk straight onto with no wait. The longest wait for a ride would have been about half an hour which was not bad at all. We just went to attraction after attraction, whatever we felt like. We did notice the park become much busier in the afternoon. strange that people arrive so late in the day? We left about 1:30 for a swim in the hotel pool and returned about 3:30, nice to have a break. The park became very crowded (hard to move) about 5pm, I'm guessing people come for Fantasmic and the fire works (well worth it). It did not bother us too much as we loved Disneyland (said I wanted to move there)! But agree they could think about limiting the number of people so it is a better experience. That would be the only negative for me. Make sure you wear comfortable shoes! My feet got very sore the second day. I wish we had longer there so our visit could be more relaxed. The rides are out of this world fantastic! Not just for kids by any means! We are a married couple with no kids and I think we enjoyed it more than if we had a cranky kid to push around! Both parks are worth seeing, but California Adventure just doesn't have the old school charm of Disneyland. We will be returning one day and will stay at the same awesome hotel. I think it is worth the money, but you have to arrive early enough to be able to do the rides without much of a line up. Had one friend who went there late in the day and avoided doing any rides due to the line ups. No wonder she hated it! Also, stay for the Fantasmic show and fireworks - amazing!
