Many parks and main squares in Guatemala have photographer making a living by taken snapshots of visitors who want to keep a memento of their visit. La Antigua Guatemala is not an exception since there are about a dozen park photographers offering the instant photography service. For about Q20/$2.25 you can have your photograph taken and printed in situ. I recommend you to use their photography service at least once so you have a souvenir and at the same time help the honest photographers make a living. It’s in my opinion, a small price to pay, about the cost of a cup of coffee, to have a polaroid of your visit to Antigua Guatemala and help our local photographers; don’t you agree?
Weather aside: By the way, this is the rainy season in Guatemala.
