Disneyland in Anaheim California.
I found Disneyland to be easier and more enjoyable than Disneyworld in Orlando, Florida. To help with dealing with the crowds, here are a few tips. First, figure out what rides to attend prior to arrival. Second, arrive 30 minutes before park opens. Third, get a FASTPASS, provided by Disney, which acts like a ride reservation, allowing you to enjoy a different ride, while waiting for your arrival time for the crowded ride. Fourth, use your smartphone and mobile apps that help with ride lines and other information.
