I might have been able to persuade myself it was "worth it" if they were still doing the dog sledding. The way I looked at it was I would be paying a huge premium and NOT getting a chance to do the excursion I most wanted to do. I'm also still annoyed that they don't have an activity for one of the ports (Victoria). You'd think with activities on only three of the "eight" days anyway, they'd be looking to do something!
