In Halifax take the city tour. You will see the Maritime Museum with Titanic artifacts and the history of the great explosion that almost destroyed the city. You will also go to Fairview Cemetery and see the 137 graves of Titanic victims. The headstones, all but one, are small and rectangular and laid out in the shape of the bow of a ship. the only different headstone is a rather elaborate, round one. It is the body of a little boy. He went unclaimed and unidentified. The people of Halifax decided he should be buried with a family so he wouldn't be alone. He was buried with a Scandanavian woman and her two children. There are Titanic historical societies on both sides of the Atlantic. Research by one in the US found that he was actually buried with his real family. The father's body was never found, but it was a couple and their three children from Scandanavia coming to the US for a new life. Halifax is a pretty city as well. You could go to Peggy's Cove but it is just a small, picturesque fishing village and half the ship will be there. Your greatest view is going to be of tour busses. In Bar Harbor take an excursion to Acadia National Park. It's gorgeous and you will have time to wander around downtown. It's a charming place. Boston? Well, there are so many things you can do. If you like history, take the Freedom Trail. It is a trail that goes by many of the places that holds so much of our history. You could go to Lexington and Concord if you prefer to get out of the city. You could also go to Marblehead, a beautiful seaside town. I believe they have tours there. I will be going to Newport and the other port you mentioned (forget what it is, age you know) both for the first time this fall. Have a wonderful cruise.
