We LOVED Disneyland! There is so many similarities but yet so many differences between DL and WDW.
Loved that you could walk everywhere. Walk from our hotel (Paradise Pier) to Downtown Disney and both California Adventure and Disneyland. And at most it was a 8 min walk. Love that. Park hopping was so easy as well, a 2 min walk from one park to the other.
Loved that we didn't have to make dining reservations and could eat almost anywhere we wanted. We ate at many table service and quick service restaurants and only had 1 TS that we would have had a 30+ min wait for, so we decided to eat somewhere else.
Loved that even though the parks were crowded when we were there (Aug 2013)... they didn't feel anywhere near the crowded levels we have experienced at WDW.
Loved the rides that were different from WDW. Cars Land was absolutely amazing. Mater's Junkyard Jamboree was DD7 favorite ride and she still talks about it a year later. DD13 loved California Screaming and rode no less than 10 times while we were there.
Loved that some of the rides that are the same at WDW sported much shorter wait times. 15min wait for Soarin... yes please. 10 min wait for Toy Story Midway Mania... we rode it 3 times.
There were a couple things that stood out to us as things we definitely missed from WDW, but we really don't count them as negatives.
- When you are at WDW and stay on site you are completely immersed in Disney. At Disneyland, you don't have quite the same feeling. You can see the highways right outside the parks. You can see gas stations and grocery stores from your hotel windows. Not necessarily a bad thing, because it can be an added convenience, but different from what we are used to.
- We really missed Epcot and World Showcase. There is nothing like that at Disneyland.
- We missed Magical Express. I know not everyone uses it, but it is such an added convenience for us in getting to/from the airport, we missed not having that opportunity at Disneyland.
You can't go wrong with a Disneyland vacation. Do your research, don't expect it to be WDW, and enjoy it!
