I just want to say that I would recommend at least one tour - whale watching.
It is worth the time & money - there are lots of whales up there so good sightings happen almost all the time. But you are not likely to see whales from the ship - the tours go to wherever the whales happen to be on a given day, but the ships always have to stick to their schedules.
I went decades before I finally saw a whale at sea - and it was on an Alaska tour.
I am the editor, but I also speculate, ask questions and play devil's advocate. I reserve the right to change my mind.
