Unorganized. We would wait at some stops 10 or 15 minutes and then have to skip some stops entirely to catch up. Had to switch busses twice in order to get to the stops we wanted to get to. Busses were PACKED. Standing room only a majority of the time. I did not pay to be on a cramped, uncomfortable bus. The local bus would have been cheaper and roomier.
While the guide was funny and entertaining, the disorganization just killed it for me. If I had paid full price I would have been pissed. Luckily I got it through tix4tonight so they were essentially half price.
If you go, go during an off period.
