The only reason this gets a 2 star is because of the tour guide and the bus driver who were both so nice and very patient. I traveled solo on this trip and expected to go on a tour with people around my age (23). But instead i was put on a tour with a bunch of high schoolers around ages of 14 - 17 touring from Spain and Argentina. The bus was extremely noisy throughout the tour, with kids kicking my chair, singing and shouting. And they also made a huge mess out of the bus, it smelt so bad and was filled with liter. Honestly if i had known, i wouldn't have booked this tour at all, was highly disappointed overall.
