Since we only have one day in Amsterdam we thought it would be prudent to maximized the exploration time by minimizing the walking.  We bought a hop on, hop off boat tour, which allows us to take all three cruise lines, all day long around the entire old city.  We usually try to take a boat tour whenever possible to get a different perspective on the city and to see more of it.  This is part of the Red Line which we took around Amsterdam, going by the main train station, the harbour, and down to Anne Frank’s house.
