The Canada/New England cruises are awesome! We absolutely loved every part of ours.
We did the Hop On/Hop Off buses in a couple of ports, which is always a wonderful way to sightsee and get around a city without spending alot of money.
But there were always cab drivers and others in every port wanting to take you around, so it depends on what you want to do and where you want to go.
