The cruise lines always have all sorts of stuff that you sign off on before you board the ship. Like ChatKat said, "legal-eze" But they are a business contracting with other parties outside the US and it is understandable they try to protect themselves. Whether it holds up is up to the courta.

It has always amazed me in my travels around the world how few guard rails there are on those hairpin turns going up and down mountains, as I remember in Switzland many years ago, and Italy on the Amalfie coast. A bus just doesn't have the chance to correct an error in steering when there is no rail. Nothing to hold it back if a mistake.

Editing here to add my sorrow at what has happened to these travelers. I had been talking with others on the board through e-mail about this, and just realized I did not focus on the substance of the event here. We never know, home or abroad, on a street here or there what will happen to us.
