[bill]

Hi
i noticed on previous threads that there is a currency exchange that you can go with on internet and collect your money at airport.However i cant find it again can anyone help also is there problems that could arise depending on your flight times (ie) wee small hours of the morning I am leaving 30/09/07 and counting the sleeps
Thanks bill
