For the budget minded traveler like me, an idea to get TO Anchorage or a way to return FROM Anchorage before or after a cruise is to check the "rideshare" section of craigslist for Alaska.
Just as an example, there is someone looking for 3 drivers to bring vehicles to Anchorage from Bellingham, WA.
If anyone has had any experiences with stuff like this, post it here...
Bon Voyage!
