Recommend the on/off trolley. We rode entire route, found what we wanted to visit and returned the 2nd time around.
Not really enough time in port to see all we would have liked.
Excursion was to Peggy Cove and the Titanic grave site. How wonderful and sad at the same time. A great excursion and guides full of info.
NOTE: Dress very warm, as it was and usually is cold and damp.
The light house boat excursion is really a nice trip to see the areas port of interest.
Downtown shopping is also easy on and off and within walking distance to ship.
Many unique shops and designs.
