Mark,
You are in for a memorable time. But remember that simply being with her, enjoying the experiences of Walt Disney World together, is more than enough on its own. But here are some ideas of what I like to do with my daughters to connect;
Play together. Interactive games like
Agent P's World Showcase Adventure at Epcot let you work together and share the memories.
Interact together. At all of the character meet-and-greets there is a lot of interaction. But you need to get involved too, especially at the newer, and more tech-rich, ones like the
Enchanted Tales with Belle. The key here is let her see you be a kid too.
Quiet down together. Consider more relaxed activities, especially ones that are off the beaten track and focus on her. I like the
Afternoon Tea at the Grand Floridian. You get to actually talk, share, and learn about each other.
As for "capturing", make sure you use PhotoPass so that you are both in all the pictures, and you capture all the experiences.
Why not write me back with a little about what she likes, and I can come up with some more specific recommendations!
Have a magical vacation!
