Who Knows? Every cruise line has different prices.
Hi there - we have found that p&o prices for beer and wine on board are equivalent to the prices in your local, but the prices on royal caribbean and celebrity are a lot more expensive, i was paying $5.70 last year on independence of the seas for a pint of draught beer, and on celebrity in 2006 i was paying around $6 for a tin of boddingtons, remembering the exchange rate at the minute is not very good. - hope this helps.
Recent reviews have stated that beer is now $7.50 on Independence of the Seas! I suppose it will stop people getting drunk.......
