I'll be in and around Antigua/Atitlan for a few days, then on to Coban to see the nearby sights for a few days before returning to GC to fly home. Trying to decide between shuttle to and from Coban vs. renting a car in Antigua and driving to Coban. Any thoughts/suggestions on this? How is the drive from Antigua to Coban? I assume there are rental agencies in Antigua? Any reason I wouldn't want to have a car in Coban to drive to the places I'd want to see around there? Thanks for any thoughts.
