I know what you mean about wanting her to love Disney as much as you do. When I took the wife for the first time a couple of years ago I made a few special arrangements in advance.
She *loves* chocolate covered strawberries (with white chocolate!), so I arranged to have some waiting for us in our room, complete with a solid white chocolate mickey mouse sprinkled with gold dust!

The funny thing was that they hadn't arrived when we first checked into our room, and we were doing the typical first day stuff such as purchasing our refillable mugs, etc. Well, we went to the Boardwalk Bakery to get our mugs, and wouldn't you know, they had her little platter of white chocolate covered strawberries sitting in the work area! I spotted them right away and tried to distract her, but she was having nothing of that. Immediately she started in on how good they looked, and could you purchase them there, etc. etc. I had to drag her out of there!

A couple of hours later we went back to our room and they were waiting for us on the counter -- along with a little love note from me welcoming her to "the World."

She then realized that she had been lusting after *her own* strawberries earlier and we had a good laugh over that.
A couple of mornings later I had made reservations for the Segway tour in the World Showcase. She didn't know anything about that, either, and it was such fun to show her my favorite park that way!
I also know her taste in food, so I made some reservations that were sure to please her palate.
All in all, we had some pretty special moments, and I'm sure they contributed to her response to Disney in general.
She just reminded me that I also made sure that every morning when she woke up I had already gotten her coffee from the bakery.

What can I say -- I love her.
Honestly, soulmates, I think you would be better off using the budget you have set aside for Gifts of a Lifetime to create special memories throughout your trip. I'd love to help you brainstorm.
