Even when you have ticked the box I would recommend visiting the customer service desk to make sure that this is clearly marked on the computer system.

the way round this is to pay in cash the evening before disembarking preferably in dollars.

Yes, this is an important point. It is most unlikely that any cruise line will offer a better overall conversion rate (allowing for any 'commission') than one's own credit card - and certainly will not better a commission-free card such as Nationwide. It is the card-holder's RIGHT to insist on being billed in local currency when overseas and this type of 'option' notice is becoming common, almost certainly because of the many complaints to both Visa and Mastercard about foreign transactions generally (not specifically cruise charges).

Thanks for that. I been with Princess twice, my partner four times and I don't think we've spotted that one! I will be checking with him to make certain this is done in future - if not already. He holds the purse strings!

Well spotted Grover of Southampton-from another Nationwide user.

Thank you for that it is certainly worth knowing. I have literally just received my cruise answer book and have yet to read it.
