DCL asks us not to wear shorts in the MDR. They have very little other requests of us while on board. DCL sets a dress code so that the MDR's create a nice atmosphere for us. And then some folks ask the question, well if I choose to wear what I want and ignore what they ask, what will they do to me? Choose a different dining experience or change cruise lines.
A PP posted that the spouse had always just worn shorts to dinner and truly didn't know about the dress code. Also stating that no CM informed them of the recommendation. Well, the CM's might not have because they know there is no informacement. And for sure the service team is not going to say anything, uhhhhh tip! But hopefully now that the PP noticed that shorts are not supposed to be worn, he will abide by the dress code.
It comes down to respecting the wishes of DCL. It doesn't matter what we want to wear for dinner in their MDR's. We should all conform to their request or as stated above, and dress accordingly or find another option.
