Got off Royal Cruise in Oct and a Family, Man, Woman and young Child were carrying off their 2 large Suitcases and one smaller one. Well they decided to not wait for Elevator and take Escalator. Staff suggested they wait, you can imagine where this is going. He(6ft 250+ pounds) fell and rolled over top his Wife(5ft 2) and 6yrs old. Was a mess, screaming, Cuts, blood, someone finally hit emergency stop. We are almost half way down as I pulled back and trying hold these Heavy suitcases rolling back over/into them. Took 10 min to get passengers below off and them separated, he laying head first on top his Family, Mom screaming, Kid crying. As bags fell over into him I was behind and grabbed them holding by one of the wheels as they were rolling down. After it stopped Passengers above me all went back up as I'm wearing a Backpack squatted down, leaning head first barely holding on the whole time...
