One further piece of advice. Take more than one card. There is always the chance of a power cut. If that happens while your card is in the ATM, it's bye-bye card until you get back to the UK.
Where possible, use ATMs, where you don't have to put the card completely into the machine and that risk dissapears, but it may take a bit of time to be able to tell the difference between the two types. The simple way is that if the place looks like a straight card slot (like most in the UK), it will take your card into the machine, and is therefore a bit risky. If the place where you put the card looks like it sticks out so that half of the card remains visible, then you are unlikely to lose the card in the event of a power cut. Of course, be super careful to hide your PIN, you will find that people will sometimes stand very very close.
