My wife & I are visiting Guatemala next month for about a week. Just starting to make an itinerary. Probably will include Antigua, Lake Atitlan, ChiChi and Quetzaltenango. We'll take a shuttle bus from the Guatemala Airport to Antigua, but beyond that am unsure of choice of transportation. When visiting countries, we like to rent cars because it allows us to explore more, but am wondering if it makes sense this time especially if we were to spend several days at the lake (after having rented the car in Antigua). Thanks.
