Correct but the OP was talking about having to buy wine midway through dinner since they would have already consumed what they brought before dinner service was over. I made the connection that they would be drinking wine at dinner in the dinning room. You also have a corkage fee if you bring a bottle from home, already opened bottle to the dining rooms. Bring it already in a glass no problem, plunk down a bottle not bought on board, corkage fee.
