Yes, you still do have to pay the $15 fee even if you open the bottle of wine in your stateroom and bring it to dinner with you. We requested wine glasses, a cork screw and an ice bucket iin our room, thinking that if we brought it opened we would not be charged but that is not the case. One evening I did bring a glass of wine with me to dinner to finish a bottle that was opened in the room and that is the only time I was not charged. Another night our assistant server did not charge us the fee and then the following night she said"Oh, I forgot to charge you the fee for the bottle of wine last night, I'll put it on the charge tonight." They really want you to purchase the wine packages that they offer on the ship.
