Thank goodness those days of assigned seatmates at meals are over! It made it quite difficult when conversations were going bad and there was not way out for the rest of the cruise!
We go on cruises to get away from the politics, stress, and news! Thank goodness we have been able to do that with Viking quite easily. Only a couple times have people been a bit too strong one way or the other, and we just bow out and avoid them in the future. If you notice, certain groups tend to "hang" out with each other anyways. Like minded people tend to gravitate to similar like minded people.
We've always had the policy of 'no-politics' as well when we meet new people on-board. Get that out of the way up front!
