I bought the 48 hours pass for this tour. It's a typical tour with three different routes throughout the city. It hits all the good tourist locations and is a great and easy way to see the city. The 48 hour pass also includes free admission to the river cruise. All three lines and the river cruise were nice. It was hop on/off with each having about 12-15 stops. You are issued a pair of headphones that connect to an automated system that gives prerecorded information. There are multiple languages that are offered. There was only once when the top of the bus was completely full. It was very hot but the back on the upper section was covered with a sun screen. It was actually the best place to sit. The lower level has very cold AC and was also nice to site, still had good views and nice when you think you're going to pass out from the heat. I think the ticket also includes the duck tour but I did not use this feature. I go on these types of tours whenever I visit a new city and this one didn't disappoint. The staff was friendly and spoke English. The ticket should be purchased from the drive when you get on the bus. Can be done at any stop.
