I agree w/Paul. Not saying it is all right to miss a drill, just that a B2B should have exceptions. I have done many B2Bs and never thought of missing the drill on the back end, but always thought it was not needed.
Its good Seabourn is not an airline. Eventhough everyone is in place for the lifejacket demo, 90% of the pax are sleeping, reading, talking, listening to their MP3 or in general not paying attention. It's the same as not being there; Seabourn would remove them from the plane.
