Looking for ideas in and around Banff, Alberta

I was in that area summer 2016 for the Stampede and touring. Stayed in Banff Tunnel Mountain trailer village and, in Jasper, Whistler. Both were fully booked when I started checking in January. I just logged on every day and got reservations in both, evidently catching a cancellation just right. Couldn't find on in Lake Louise but on the hwy a mile or so south of town there is an overflow area that is dry camp without reservations. Plenty of room when I was there.
