I have to agree. Any travel to the polar regions is fraught with weather related issues. It is especially relevant given that expedition cruises are pushing the boundaries of what is regularly possible, especially during shoulder season. Is their marketing bordering on false advertising?
Not thinking (my superpower) I almost booked a trip back to Greenland for next June. Its hard to get into some of these places in August. June would be iffy at best. For example, last August Scoresby had just opened up, the ship before us couldn't get through.
So do the cruises lines have a bigger responsibility (other than fine print) to warn folks that these weather cancelations can and do happen all the time? A good TA would.
