Find Your Cruise
We have cruised with RCL and their drinks are quite expensive and off course there is always the service charge added as well which is about 18%. The best way we find is always to buy a wine package on the first day which is cheaper than buying each day, and you can choose fromaabout 5 selections for the wine you like.
Sorry Mr Lewis but the OP asked about Celebrity. There is no wine package offered on Celebrity, secondly the wine prices are not expensive, neither are the drinks IMHO, and thirdly the gratuity added is 15% not 18%.
When we sailed on the Infinity to the Panama Canal and mexico we had a wine package. We usually said with RCL whcih is part of the Celbrity Group and their wine packages are excellent, but do include a service charge, which we always accept as it is part of the holday and after spending over £2000 each for a cruise why penny pinch about a tip. It is always shown in the brochures
The Infinity is the only Celebrity ship where they are currently testing a wine package - the OP is on Millennium which does not.
Here is a link to the wine prices http://good-times.webshots.com/album/564642780vYlqpC.
There is a good range of wines in the $25 to $35 dollar range and as you maybe drinking before/after your meal you can make the wine last two nights as the will re-cork and bring it back to your table the following evening. As far as drinks go my wife drinks Gordons Gin/tonic and I have Captain Morgan with lemonade and that come to $12.95 or about £6.60 My tip is just don't order gin/tonic as they will serve you the more expensive drink check the price list and be specific that way you can enjoy your drink at the best price. I always remind people if you went into a four star hotel and asked for a drink what might it cost and on that basis I have never thought the prices were high, you do in fact get more than a 1/5th of a gill. I always find too much ice and mix so be specific about this as well.
