I just got back (today) from our first trip to
Disneyland after multiple trips to WDW. It was odd to not plan your week around a dining schedule. We only made one ADR for Goofy's Kitchen and just figured it out for the rest. I was disappointed with the food options in the parks.
The thing that through me "off my game" the most was the line setup. Most rides have their lines largely outside, even most attractions board outside, which compared to WDW makes you think this wait must be insane, look at that line outside.
They need to implement a WDW style ticket system, because the current setup is to treat you like a criminal. We left one park to go to dinner with plans to go to the other park after dinner. I saw people getting their hands stamped, but as I had a park hopper I didn't see why I needed to get a stamp. I learned after dinner on attempting to enter the next park. You have to show your ID for all adults, they make sure it matches your ticket, then check for the stamp. Despite my ID matching the ticket I was read the riot act about how I wasn't going to be allowed in. As I waited to be let in I did notice the nice large sign claiming Disneyland uses items known to cause cancer.
We spent 3 days in Anaheim and did everything. It was more than enough time.
