well, if you did go by the little advice I gave (travelling through New Brunswick then onto PEI), the ferry that crosses from PEI docks in Nova Scotia about 10 miles from Pictou NS, and is very close to Cape Breton, home of tons of festivals and nightly ceilidhs (although they would be getting sparse by the end of September). The land cools off quickly in this area in the evenings, so pack a warm sweater or two for your music circles around the campfire :)
