We brought a bottle of Champagne on board, and brought it to Lumiere's for formal night. Our server didn't charge us the $15 corking fee. Don't know why. It did reflect in his tip (I expected to pay it, and did, one way or another...). The Champagne we brought was not offered on board, and was a very good one that was given to me from some friends to celebrate on board with. The ship does indeed have an adequate selection on board, though not extensive, IMHO (and even their reserve list was not very extensive), so, if you are looking for a nice wine and don't require a wine list that is a book, you will be very pleased with their selection.
