We were chosen to do this last july. We didn't do or say anything different when we checked in, they just asked us our names and told us to be seated in the waiting area like everyone else. After about 5-10 minutes a nice lady walked over to the waiting area and called out our name, she then quietly asked us if we would like to be the family to ring the bell we said yes, she said she would be back in a few minutes. When she came back she took us to the dining area, we waited a couple seconds for the characters to come out and the cm's took a group picture of us with the characters with our camera, then we all went upstairs for the opening. They also served us first out of everyone in the restaurant.
