My fiancee is set on going on a group tour to Chile with a bunch of our friends. She thinks it's safer to go in a group, especially in cities like Santiago and San Pedro de Atacama, which are the two we would visit. I want to know if it's true that it's better to go in a tour group, or is Chile safe for independent travellers. Some of us will have kids with us, if that makes a difference. Should we be concerned about safety in Chile?
