We arrived in Skagway okay. There were a lot of loud school kids on the ferry, which provided one of the quotable quotes from this trip: "If you get hurt, you'll bleed all the way to Haines!"
The M/V Matanuska was pretty nice. We got a cabin for the trip, which gave us a base of operations, as well as a place to snooze and shower. There are public showers, but having a private place to lay down (as opposed to slouch in a chair) and sleep, as well as shower, is much nicer.
