We signed up with a tour guide from the train station that took us about 4 blocks to a small office to sign up. There was one person and they were taking credit cards and doing the slips manually. The line was long and it took a long time. Then it took over one hour to get on the bus once we paid. The line at the train station was long and their buses did not come along fast enough for that location. Once on the line, it seemed to go okay after that but we only got off on two stops.
