You are coming here during the very best time of the year.
No need for reservations after Labour Day. You might find some attractions and campgrounds closed such as the boardwalk shops in Cavendish PEI but no worries, the best attractions and restaurants will be open, not crowded and some even lower prices in September. The fixed link is a 13 k (8 Mile) bridge that is quite a drive in a motorhome, safe but exciting just the same.
A good example of bargain prices after Labour Day is golf in PEI. World class tracks at rock bottom costs, can't be beat.
Check out Kiwanis Ocean Front Camping in St. Andrews NB in September. Through the week the place is almost empty. The small sites are not an issue and the seafood restaurants are all open.
Hartt's Island Campground near Fredericton is right on the Saint John River and water front sites are available. Visit Fredericton area Sept 13th to 18th to party at the Harvest Jazz and Blues Festival, the largest music festival in Atlantic Canada. It features many American performers.
Halifax has a municipal campground in the city on the city transit routes. Downtown Halifax is a must do while here. Shops, restaurants, bars, shopping and history all within a short walk. Peggy's Cove, Mahone Bay and Lunenburg are all an easy day trip from Halifax.
If you have time include Cape Breton. The Cabot Trail is a drive that will provide the most amazing vistas and get your blood flowing at the same time. You literally drive on cliffs hundreds of feet above the ocean. Best done with your toad!!
Welcome and enjoy.
