I agree. Flying into Anchorage and making your way to Seward on the same day is, in my opinion, too tight a schedule in case there are delays at point of departure, luggage issues, transfer to port etc.... I just don't see the need to trot out road closures, floods, fires, plagues of locusts and whatever else that could delay a traveller when there are all sorts of common and mundane reasons that could lead to travel problems which could most likely be avoided by coming in a day early.
