I will be traveling Guatemala to visit family and friends and will most likely not be doing GC or touristy places. I was looking into renting a car but found great discrepancy in prices. The best prices are offered by National (through expedia, kayak, etc.). Has anyone used them? Are the cars up to par (as the online description is " type of car or similar")? Should I instead go with a well known brand (hertz, alamo, etc.)? Having worked in marketing I know that these companies are not necessarily better they just have better exposure. Any help would greatly be appreciated.
