Tourists face a world of dangers. But with the right advice, most hazards turn out to be manageable.JIM VAN HOUTEN, A FINANCIAL planner from Phoenix, Ariz., was on a tour of the Middle East, but by the time his group arrived in Egypt, most of its members had opted out. ``We started in Israel with 320 people,'' he said during a visit to the Valley of the Kings, the stunning burial site outside Luxor. ``Only 62 people came to Cairo, and only 16 of us came down to Luxor.

The most extreme risks are so well known, and so rare, that tourists are unlikely to encounter them: kidnappings in Yemen, beheadings in Chechnya. Long-running civil wars have turned some i...
