The other guys have said it all really, we never take any expensive jewellery or watches, the worst bandits are the close family whom my wife finds it very difficult to say no to when they start admiring what she`s wearing.
Bad things can happen anywhere, most of the kidnapping in the P.I. is on the Chinese and Koreans for ransome. Dont walk around looking like a tourist, with a map in one hand, be careful who you accept a drink from etc etc.
My daughter ,at 20 and blonde, backpacked around Luzon right up to the rice terraces and South around Samar without problems.
I like Manilla and always feel safe,but I always try to be aware of whats around me, the safest place in London is Soho.
