I think they only do a soft drinks package. A lot of lines don't want to encourage a 'booze' culture.
The soft drinks are very expensive.normal size can of coke £1.20 bottle of water £1.10.
Was on O,V 2 in august this year and i rang the travel agent to ask this question.I was told O,V dont do the drinks package deals.We did the med though, so the caribbean cruise could be diff,Check with your travel agent,enjoy your hols.
Update - they do do other packages, wine for instance. Go to the top left of this page and in tiny letters is the word "sitemap". Click on this, then click on drinks packages. There is info there for most cruise lines ! That sitemap is really useful.
Thanks to all for their responses - particular the tip relating to the sitemap. I should have mentioned that I was looking for a soft-drinks package!!
