We were lucky enough to be able to the "family of the day" at Epcot one day during our 2004 trip.
We were NOT the first ones at the rope, but there happened to be an opening at the rope and big enough for my 2 kids (then 8 & 10) to stand in front with DH & I behind them. There was a CM walking along the rope talking to the people and she was walking our way! Luckily from this board I knew what she was doing.
Wehn she was talking to the family next to us I was PRAYING she would move on... and she did. She started talking to my kids and asking them all sorts of questions, unfortunately my then 8yo is very shy and really didn't want to answer. But there I am with this HUGE grin on my face, talking, laughing, etc.
DH is looking at me like I am nuts, but I tell him to just let me do the talking, and follow along.
She asks my kids what one thing would make this trip very memorable, and both my kids shrug their shoulders, and there I am jumping up and down with my hand in the hair saying "pick me, pick me... I know the answer"
The CM, by this point, is laughing, and tells me to tell the kids the correct answer... to which I reply "Being able to be family of the day and open Epcot would be the HIGHLIGHT of this trip!" Both my kids & DH have this look on their faces like I am out of my mind.
So we were picked, and it was really fun. While we were waiting for the character bus to arrive, I had a chance to explain to DH & the kids what was going on, once they understood they thought it was very cool to be able to do this.
We got a certificate for being "family of the day" and a FP for 1 ride at Epcot.
