When I was at MGM 3 years ago waiting for Fantasmic to begin... the preshow CM let a bunch of kids come up on the stage and use the mic to say stuff to the audience and answer questions... He also used it for announcements, "So & So, your wife is looking for you, she's over in that section there, etc."
Then this girl was in line and asked to say something to her boyfriend... she said '"You know that question you asked me yesterday at the Magic Kingdom? Well the answer is "Yes!"'
The CM asked her why it took a WHOLE DAY to answer the question!
But anyway my point is.... YOU could propose to her in front of the entire audience... YOU could sneak in line and ask the CM if you could ask your girlfriend a question... I think they'd let you..
Last night I was at a Red Sox game and on the Teletron, they put an announment "Hey Kathy in section 25, row 14, seat 14" ......
then on the next screen they wrote "Tom wants to ask you a question..." then on the next screen "Will you marry me?"
I was in a section on the other side of Fenway, so we don't know what the answer was... we just wished they had shown them ON the teletron when she answered...
Whatever you decide-- GOOD LUCK!
