I think a Disney park is what you make. We've been going weekly to a park since ds was 6 weeks old, for a few hours out of the house. He is now 2 and loves MGM.
Of course, he loves playhouse Disney. He enjoys the Great Movie ride, except for the video section at the end. That's too long to keep his attention, and usually when I pass him his spill proof sippy cup. He loves to visit the characters.
We've had some of our most magical moments at Disney with the characters at MGM. The voyage of the Little mermaid can be intense for a toddler. My son hates to get wet, and we've discovered sitting towards the left of the theater get's less "splash".
The animation tour he likes, especially the games afterwards. We have to hold him up, but he really likes pressing the buttons and watching things happen.
Obviously Rock and Roller and Tot are out of the question.
He loves the Beauty and the Beast show. We sit either to the left or right side of the theater and put him on the aisle seat so he can see.
He loves the Backlot tour. We have to tell him ahead of time about the loud explosions, but he thinks it's funny to watch the people get wet. When it comes to the fire part of the tram ride (catastrophe canyon) I put my hands over his ears and we watch for the fire. A couple times we did that while the stunt show was going, so the stunt men waved to us from their cars, as they waited. We also discovered how little room back stage there is for error at the stunt show, when one car after the other comes zooming by back there. That was pretty magical.
Across from the back lot tour entrance is a huge coca cola bottle. He loves to get wet from the mist that shoots out of it.
There is a playground at MGM it's called Honey we shrunk the kids. My son loves sliding down the film slide and standing by the water fans and getting soaked. This is one of those places where you can't let the toddlers on their own, there are too many nooks and crannies, and the older children are often unsupervised.
The cars from Cars come out at various times for meet and greets as does the Power Rangers. My son has no idea who the Power Rangers are, but he loves watching their grand entrance.
At Al's toy barn are the characters from Toy Story. He loves visiting with them too. We don't bring an autograph book, he just interacts with them, and we take his pic.
There is also the afternoon parade that a toddler should like. We usually find a spot after it's started. He doesn't seem to care if there are people obstructing his view. He's happy with what he does see.
Oh and Muppet Vision is great for toddlers. Ours usually doesn't wear glasses, but he hold them. He loves Kermit!
