Hey Man...
We made it to Lunenburg on our vacation a couple weeks ago. Nice place! We ate at the Old Fish Factory (I think it's called). The people in NS are super nice. I accidentally strolled into a back office looking for someone to make meter change, and some random accountant made some change and recommended better, all-day parking. Even in Montreal, a city bus driver trusted we were taking the subway, so he gave us a "Reverse Transfer on Trust" -- aka free ride.
Your route looks similar to our cruise route -- We started in Boston on to Bar Harbor...Halifax, Sydney, Charlottetown, (Northumberland Straight), Quebec City, and Montreal. I hope your weather pans out better than ours (fog, mist, cold) but a what a great experience. Fort Louisbourg (and the town) was neat (had the best Pistachio Cake ever). Canada Day in Canada can't be beat either
Enjoy the trip and keep us posted! The waves were a bit choppy out of H-fax... I hope they smooth out for ya
