I just came back from DLR Feb. 16trh. We were there for a week and spent 5 days between DLR and California Adventure. Having been to WDW approx. 25 times, I love it and it feels like home. I must say you don't have the same immersion as at WDW, but DLR and California Adventure were great. Really enjoyed both parks. I was scared to go on California Screaming and Mickey's Wheel. I went on both and loved California Screaming. It was great. Mickey Wheel was ok and I did the stationary gondola. Radiator Springs Racers was really something and made you believe you were at Radiator Springs. Lots for little people to do.
A lot of DLR's attraction are superior to WDW's attraction. A lot more detail and longer rides. Toontown is wonderful for little kids and so are a lot of the attractions in Fantasyland that WDW doesn't have. Pirates is so much better at DLR, but not Haunted Mansion. WDW's splash mountain is more better and a much better view when you are at the top before the drop. Space Mt. was a smoother ride than at WDW and you sat next to a person and not single file. Also the way they handled the handicap was really interesting. You got into the vehicle and the other vehicle moved sideways off the track and the handicap car moved over and took it's place.
You can still sit in the front of the monorail or the cone in the back. It is more an attraction than transportation and at DLR runs on the side of the city street for part of the way. I think it is better at WDW.
There Toontown is better than what WDW have and so is DLR's Snow White and Mr. Toad. Peter Pan is better than at WDW.
WDW's castle is bigger and makes more of a show, but DLR's is very pretty and has an attraction that you walk through about Sleeping Beauty. Very nicely done.
The food at WDW is superior than at DLR and WDW knows how to move people better. Just my opinion. At DLR they take your picture and match it with your card everytime you enter a park. You also still have to get your hand stamped when you leave the parks if you want to reenter. When we entered DLR through the handicapped line, it took 3 people to check us in. One checked our picture with our card, then we handed it to a person who handed it to someone to scan into the machine. No running it through the machine and no fingerprint. It seemed they weren't as up on things as WDW.
Oh, the riverboat was being worked on and the Columbia was running. That was really neat. They also used it in Fantasmic with Captain Hook and Peter Pan on the wires high up on the ship.
Overall I really enjoyed both of the Disney parks in Anaheim, but I didn't feel as sad as I do when I leave the Magic Kingdom at WDW to go home.
