Thanks to all peoples ideas and info,I just need to figure out a way to get someone to photograph the moment when I ask! I am probably going to propose at the well just because Im shy and my girlfriends shy too...
my best friend got engaged at the mk in front of cinderella's castle, and her fiance gave a photopass guy a heads up. they got some great pictures out of it, and the photopasser was even out of the way, so my friend didn't see it coming at all. i'm sure if you find a photopass person and let them know what's up they'd be willing to get a picture of you guys anywhere.
