Not that this has anything to do with self assist, but toting luggage in general. I have also seen people who walk on the ship with every bag they have. Are they afraid their bags won't make it onto the ship from the curb? They don't trust the long-shore men? They end up lugging all the bags around until the cabins open up. I say - ditch most of your bags (I carry a small tote with my camera, etc) at the curb and enjoy yourself once you are on the ship - don't worry, your bags WILL make it on.
