Yep. First time buttons are great as is photo pass.
A bit more on the theoretical, I would say the following things.
As odd as it sounds, pack your imagination. What I mean by that, it is all too often easy to experience Disney THROUGH your kids. That is a great part, but I think the true magic of the parks is when everyone experiences it together sort of. Remember being a kid and being in your backyard with that cardboard box or a snow fort, and you had an entire new world in front of you that existed in your head? What Disney does best is creating the ultimate set of cardboard boxes for you. ha ha. As you wander around, challenge yourself and everyone to try and come up with the stories that go with the surroundings. While some attractions make it blatantly (painfully?) obvious, much of the magic comes from the little nooks and crannies around that are left for you to fill in the blanks. The best part of that: you and your family will be able to do that forever. Although we sometimes try to abandon it, your imagination is lurking in there, and Disney is perhaps the ultimate place ot use it, especially as an adult. I guess I would say encourage that part of you, and allow yourself to be lost in your own fantasy/version of your surroundings. That makes it you (and your family's) personal Disney World.
Have a magical trip!
