I think Mr Blyth below must be using the wrong ship as P&O use sterling. We have not yet been on Ventura (go in Oct) but prices on P&O ships are usually the same. They seem to work out a little bit cheaper than a good hotel. Wine at dinner can be bought by the bottle, carafe, or glass and there is an option of buying a wine package of around 6 bottles. A half litre carafe of house wine is around £7. Gin & tonic around £2.50. The wine waiter will keep any wine not consumed for the following day. Unlike some other cruise lines there is no service charge. The price on the menu is what you pay. There are cocktails of the day at special prices and sometimes there are offers on champagne.
Gin and tonic $6.50 but I believe a larger measure than back home and wine from $20 upwards. I would think you would get a reasonable wine around $30 and you could make it last over two nights as they will re-cork it and bring it back to your table the follow evening. We do this as we have other drinks before and after dinner and don't really want to end of legless - cheers.
Drinks were normal UK bar prices. Gin n Tonic £3.50, wine large glass of house £3.75. Pint Stella £2.65. Bottles wine start at £14. Cocktails £3.50ish. Not too bad at all, don't you think ?

We were on Ventura in June, we did not find drinks expensive at all. We would suggest for dinner you try half carafe of house wine, either white red or rose for approx. £6.50. Really good value.
Prices are in line with Pub prices. Two glasses of house wine (standard size) costs approx £5.35.
We went to the Caribbean last year with P & O Oceana this year in September we are going tothe canaries on Ventura. The bar prices and the wine at dinner we found to be very reasonalbe comparing with prices in bars or hotels at home .
