I am off to the USA for 3 weeks in October to get married . Can you advise me on the best way to take my currency. I have had some advice to use a Nationwide Current account to withdraw cash from atm's and also to pay for goods. I have always taken travellers cheques in the past but as its our Wedding and Honeymoon i will have a fair bit more cash than usual.I was also told that fopr purchases to use my Post Office credit card.

many thanks Donnie
