I am sorry but I have learned virtually nothing on this trip. There was no multimedia presentation in the beginning. We were taken to the church and sat 2 hrs straight during the whole mass, gospel was maybe 30% of the whole experience. Then the guide walked us through some streets but like I said, I have learned virtually nothing about the history of the area. I am not even sure if the guide has any professional training, for sure he had no historical background but also did not really care if we understand what he was saying (normally the guides speak loudly and clearly since they are aware most participants are not native English speakers, but not in this case). Wouldnt pay USD 45 again.
