You are right to be concerned. US State Dept has Guatemala ranked at their second highest threat level. "Level 3: Reconsider Travel" (the only higher level is "4: Do not travel").

Based on the what the State Dept is saying, no way in hell I'd take my family there. I am not trying to be a dick. Read up on it, it's not a good place to go.
This is just SOME of the warnings on the web site. They recommend hiring security escorts through the government there.
Crime: The crime threat level in Guatemala is critical. The Embassy has no reason to believe that U.S. citizens are being specifically targeted, although criminals in Guatemala may assume that U.S. citizens and their relatives have more money than average Guatemalans.
- The number of violent crimes reported by U.S. citizens and other foreigners remains high and crimes occur even in areas of Guatemala City once considered safe, such as Zones 10, 14, 15, and 16.
- The Guatemalan border with Mexico (and in particular the northwestern corner of Petén) is a high-risk area due to large scale drug and alien smuggling.
- The border areas including the Sierra de Lacandon and Laguna del Tigre National Parks are among the most dangerous areas in Guatemala. The U.S. Embassy takes extra precautions when U.S. government personnel travel to the region.
- Reports of sexual assault remain high. Support for victims of sexual assault is lacking.Theft, armed robbery, and carjacking are the most common crimes against U.S. citizens who visit Guatemala, and travelers have experienced carjackings and armed robberies upon leaving the airport. Victims have been killed when they resisted an attack or refused to give up money or valuables.
- Pickpockets and purse-snatchers are prevalent in major cities and tourist sites, especially the central market and other parts of Zone 1 in Guatemala City. In a common scenario, an accomplice distracts the victim while an assailant slashes or simply steals a bag or backpack.
