last time we went in Mid Aug, 9 days total
because we drove from Vancouver, and on way back we stopped by Edmonton to visit a relative.
We booked our B&Bs in March/April to make sure we got our first choices - Ensuite, and if possible, separate entrance. At Jasper we had a wonderful B&B - actually no breakfast, it is a second floor Big studio with kitchenette. It has its own entrance so it is very private.
