I think one thing to keep in mind when camping in the Canadian Rockies that there are very few "bad" places to camp. In general, there are enough trees and space that even crowded campgrounds are still extremely enjoyable. People camping in the campgrounds are generally quite and reserved. In fact sometimes it's the off the beaten path locations that can become noisier due to ATVs and lack of regulation.
Even though one may want to plan as to not miss out on anything, you really can't go wrong. We usually just go with the flow and take even day and adventure as they come.
