campgrounds along banff-jasper parkway

Thanks Idaho that helps knowing someone else the same size fit.

Canadafan, yes I am aware of the popularity of these campgrounds as I live in Calgary and have driven the parkway frequently, just never camped in the non reservable sites. I will be coming from Two Jack Lake where I have reservations for the weekend prior, so plan to get an early start on the Monday in hopes of getting a site.
