Pick-up and drop-off at the airport is very convenient, but the "first day" and "second day" on the itinerary are not accurate at all. Basically, the travel agency arranges the daily itinerary. We only know the day on the itinerary tomorrow is twelve hours before departure, and the tour guide may be different every day. One of the problems was that the first day on the itinerary was to go to the Salamanca market, which is only open on Saturdays. So I signed up for the group and bought a ticket and chose Saturday as the first day of the trip. Who knew that the travel agency finally arranged a third day? It was my first day's itinerary, but I couldn't go to the market. The travel agency did not reply and the tour guide said that the products sold in the market were the same as in the store. The problem was that in the end, I found that there were no stores nearby that the tour guide mentioned. Other than that, the rest of the trip was fine.
