I definitely recommend taking this train excursion if you haven't already. Yes, it is a 4-hour trip, but I would rather spend 4 hours seeing Alaska like this than a 1 hour in a cramped bus. We chose to cruise Alaska instead of somewhere else, because we wanted to see Alaska. We could not afford some of the more expensive excursions, so this was a pretty good compromise that enabled us able to see parts of Alaska that you can’t see unless you take this train or fly in. The last half of the trip, not being accessible to those who take the Alaska highway.
