I'm not sure of the exact timing. We're going next month. But I understand there is a late train that leaves Seward around 6:00 and gets into Anchorage about 10:30.. That may not give you time enough to get to the airport though. If you don't take the early train, you don't get it through Princess. Go the the Alaska Railraod site to get more info. Hope you enjoy your cruise as much as we intend to! Can't wait!
