We disembarked the Dawn on the 2nd November, we did see a couple of men wearing blue jeans in the restaurants after 6:00 pm. I guess no one is around or bothering to say anything, he was wearing a jacket. On the Spirit a few years ago, we went to Atlantide with another couple we had met on board, it was Informal evening, the Maitre D asked him to go and put a jacket on.
