He's got a uk passport, nobody will be nicking that@Horley Chorley has listed all the places you could think of, and more.
But you absolutely need to watch your wallet and phone. 2 mates of mine had their wallets lifted when someone "befriended" them, my son has his phone and wallet nicked. It's absolutely notorious for it. My son said the police station was full of tourists queuing up to report their wallets/phones/bags/ watches nicked.
Just take a little money out with you and lock.the rest in your hotel safe if you have one, and take only one credit card out with you. Take a copy of your passport out, but not the original.
Enjoy, but be careful.
