Jimmyd, I'd phone the company you have the credit card with and advise them what you intend to do. You just don't want any hiccups when you get there. I was in Cairo 2 years ago and saw a painting I fell in love with. However, in front of everyone my card was not authorised twice. This was even though my credit limit is €15k and I'm one of those people who hate paying interest so it is paid in full every month. Eventually, I got through to Visa by the gallery letting me use their office to make the phone call to Visa at home in Ireland. I was then told it was because there was a lot of credit card fraud in Egypt. Wheter there is or not, you don't need the hassle when you are away, so a quick call now might possibly save you wasting a half day out of your holidays trying to sort finances when you are trying to get away from all that.
