Wear your bag across your chest.
Make sure your kit is insured for theft, or damage when abroad.
Never keep valuables behind you - in a rucksack or back-pocket.
Carry only the money you will need for the day and keep the rest locked in your room safe. If you see something you want to buy, make a note of the price and go back for it the next day with cash.
Don't use your card. My mates wife used hers in Portugal with us last year and some git cloned it and booked airline tickets to Japan with it.
Don't get into large crowds or let yourself be jostled, as that's where most pick-pockets hang out and stalk their targets.
Let the wife/girlfriend handle the day's money so you can blame them if it gets nicked...
Or keep it safe in your camera bag, which will never leave your side, and have just enough change in your pocket for ice creams and coffee, or spread the cash around your pockets.
Above all enjoy your holiday and don't let anyone spoil it by being a bit lax.
The other advice above is paramount. Have a nice trip you lucky ...........wotsit.![Big Smile [:D]](/emoticons/emotion-2.gif)
PS. I always take cash with me - about 100 quid a day. I put each days cash in an envelope so I know what I have got. Any money over at the end of the day goes into the following day's kitty.
You can see how mean and petty I am...![Wink [;)]](/emoticons/emotion-5.gif)
