The trolley tour of Boston, offered as an optional, is the best way to see the entire city. Take it at your own pace, but I would suggest stopping off at the USS Constitution and Fenway.
I went on two tours alone...I made life-long friends along the way! That's the nature of Contiki.
Make a visit to the Staropramen beer factory, Staropramen is a beer made in Prague and you can tour the factory. It is close by the metro station Andel.
