Congratulations!!!That is a beautiful story (made me all teary eyed, bringing up memories and all that good stuff)...
Thanks for sharing...
(oops - did I just out myself for stalking the wedding section of the Dis? LOL)
If you're looking for a more quiet place, how about the wishing well near Cinderella's Castle? It's a very romantic little spot. And you can begin with. "Do you know what I wished for?", then go down on one knee . . .
There's also the small storytime area near there that's desserted when there isn't a show going on.
