I prefer to take my children, ages 2 and 3, to Disneyland over Disneyworld because it is closer to where I live in Arizona. Both are very expensive and any help in the wallet to help lower the cost is nice. Also, I find that Disneyland is better for children under 5.
Disneyworld is closer to most of the US population, including the Southeast, Northeast and Midwest, and Disneyworld is considerably larger than Disneyland. By all measures, Disneyworld is better than Disneyland, and it was also the first of the two theme parks. Disneyworld has more attractions and hotels than Disneyland, as well as nearby theme parks.
I feel every single time I am at a Disney park it takes me away from the real world I really get to experience the Magic of everything around me that Disneyland does have but not as much as Disney world. I think there is more to see more rides to ride and a lot more shopping. Disney World is better than Disneyland! Kids love it and it is warmer than in California. Plus with new rides always coming out there are new things every single time I go.
I feel Disney world has more creative rides than Disneyland. They have more hotels and parks. Plus new technology. I live close so it is easy to get to. All the rides, even the not Disney made like rock and roller coaster, have there own Disney flare. That is just my opinion.
