My husband and I are considering a July 2008 trip to Cusco and Machu Picchu with our children ages 17, 11, and 8. This would be our first trip to Peru and have read we would need to be very concerned about safety. I also would like to do our own planning, not going with group. Just be aware of area and not display any jewelry or cash? Any different then any US metropolitian area? Any suggestions for travel in the area or with kids would be greatly appreciated. Thanks!!
