Hi, We have sailed with Celebrity before, but since then I have stopped drinking any alcohol,although my wife likes a tipple!!...We are off in June to Iceland in Aqua class and it includes the standard drinks package. Am I able to get zero alcohol wine on this or beer ? ( I know I can probably get a 'mocktail' or soda ), but I like the odd zero alcohol drink. I am concerned that it may be extra and plus I end up forking our the 20& gratuity on top which seem a bit unfair and expensive!!!
