Enjoyed this trip and it was good to see some of the Dutch countryside. A couple of negatives - the air conditioning on the coach was not working and it was very, very hot. The group was too big and at times it felt like we were being herded like cattle.
The boats were comfortable and warm and the commentary was interesting and informative. Although there are 3 lines, the green and red lines follow more or less the same route and stop at the same places. All the lines go to the museum stop and we found ourselves there several times when trying to get somewhere else. Although its a fine way to get around Amsterdam its not that quick or efficient.
