We had originally signed up for the Antigua Self Guided trip, but ended up upgrading to the Colonial Antigua City Highlights as we were in the van with 4 others who were on that tour. Our guide, Fausto, nicely offered us this upgrade to join them on their tour and we were glad we did. You think you can tour on your own, but you experience it more richly when with a knowledgeable guide. We had a 90 min. AC ride from Puerto Quetzal to Antigua while Fausto spoke about the area and history. The walking tour was informative and the history quite impressive for this city. Lunch at the Convent of Santa Catalina under the arch was very good. Thank you, Fausto!
