I was once a cast member @ Epcot with the FriendShip boats, and me and a co-cast member were doing our round in the lagoon, and we had this kid no older then 5 getting on the boat with his parents...and he started making a big fuss when he got on the boat about how there wasn't any seatbelts and that he couldnt ride on the boat without seatbelts....his parents were trying to calm it down, but it just wasn't happening....SO in quick response i went over to him and told him Mickey had invisible seat belts so the boat doesn't look cluttered, and i had the whole Boat pretend to buckle their seat belts, and once that happened the boy sat down and got quiet and said ok if Mickey says so, Mickey says so, i can ride this boat with his invisible seat belts (As he buckled his)......and we were on our way!!
I thought it was cute!!
