Hi again, Karen16! Thanks for all your candor- I really appreciate the excellent advice from someone who's familiar with Alaskan travel. I saw you recommend TourSaver on another thread- can you do these tours at ports of call on a cruise, or are they only feasible when you're travelling on your own? I know sometimes tenders will only take people who've booked the ships tours on early departures, etc; Is it possible to do? Have you?
