We just got back! Just a warning for people booking Misty Fjord float planes in early June of next year. None of the early AM ones went out on our ship and people were left with no tours because our ship was full. We had AMZING weather all cruise but of course it was raining in Ketchikan (rainiest place in North America) so you can expect it will most likely rain. If you book that I would book a departure after 9am as those seem to go out after the fog cleared a little. Just my observation as I wasn't booked on one but they were making the cancellation announcements all morning and i talked to a few people who had to do the duck tour because that was that was available
We ran into the same issue on our August 23, 2011 cruise. We were able to get on a later flight, but our return time would have been too close to dinner (pirate night). It was super foggy all day, and even if we took that later flight, it appeared that the visibility still didn't clear up. I would recommend a non-flight tour that day, as our boat/flightseeing tour was also canceled due to the choppy waves/poor visibility.
