We will be there in late October for 3 days after a Silver Seas cruise from New York. Suggestions for things to do? I know many of the tours etc end in Sept.
Notre Dame Cathedral, Sailors Church (Notre Dame de Bon Secours), Marche Bonsecours, Mary Queen of the Worl Cathedral and City Hall were all worth seeing.
Get an answer from Hotel Le St-James staff and past guests.
