Landings are restricted to groups of 100 or fewer people. That’s not especially practical for a cruise ship with 2000+ passengers. We were a little town about this point. But, utlimately, economics (and no great desire to walk on ice — I have a poor history) won out — this cruise was about 1/2 the cost for the 3 of us of a single fare on an expedition ship. So, if we love it, we can afford to go back later when Emerson’s older.
