Just a thought. If this proves to be correct , I think it may well annoy some of those who have cabins with a balcony rather than those who have inside or restricted viewwith no balcony.
It must be pleasant to sit on the balcony with a nice chilled glass of vino or g and t.Far more chilled than a noisy pub/bar.
However I think the wine was priced on par with a pub/restaurant and was excellent value and quality.
I didn't take any alcohol on board. Personally I couldn't be bothered to carry it and I certainly wasn't going to buy it in the Baltic countries.
