Hi Jaime,
Congratulations!!! Getting engaged at Walt Disney World sounds magical.
A friend of mine got engaged at the Magic Kingdom a couple of years ago. He used a service called Gifts of a Lifetime. Basically, he and his girlfriend were sitting around the hub in front of the castle. He left to go get them a Mickey Bar or something. A member of the Gifts of a Lifetime presented his girlfriend a letter that sent her on a scavenger hunt. When she reached her destination, he was waiting with a glass slipper and a ring.
The company does a Pre-Event Questionnaire to help customize your surprise. To find out more about this, go to

If over the top isn't quite your style, how about a nice romantic stroll along the Polynesian Beach or the Boardwalk? Time it so that you're popping the question just before the fireworks are scheduled.
Hope this helps. Have a magical vacation, and I look forward to hearing from you again when you're planning your honeymoon!
