If I remember correctly, Tunnel Mountain Village II is the only Banff campground that has public bus service that runs directly into Banff. If you do not have a toad or are the only PU for 6 people, you might consider staying here and taking the bus into Banff (1.6 miles). My wife and I loved leaving the RV at the cg and jumping on the bus to go sightseeing in Banff and the surrounding area. I would not recommend driving thru Banff during tourist season because of all the traffic and RV parking issues. If driving is not a problem, then just about any campground would work for you as long as they can accommodate your length.
