We stopped in Calgary for a few days on our way to Tunnel Mountain in Banff last July. We stayed at Bow Rivers Edge in Cochrane and commuted into Calgary. The campground was very tight and more like a well manicured parkinglot, but it worked for us since we only used it to sleep while we toured Calgary each day. On a side note here are a few items that we didn't find out until we were in Canada:
1. Credit Cards- I called my card companies before the trip to see what extra charges they might add. I only carry a Visa and Discover Card. Discover is our favorite and wasn't going to add charges. Found out that not a single place would take Discover. Most folks had never even heard of it. I was bummed to have to use my Visa, but it turned out OK.
2. Showers- I was surprised at some of the commercial campgrounds (Bow Rivers Edge was one) they charged for the showers. There were 5 of us so sometime we like to use the campground showers.
3. Laundry in Banff- There are no laundry facilities in the campgrounds in Banff. You will have to use one in town. Don't remember the cost since we ended up handwashing the needed items so that we didn't have to sit in the laundromat.
4. Mosquito spray- Bring as much as you can buy!!! I have never seen mosquitoes that big! Keep in mind we went last summer after all the big flooding, so maybe that's not the norm.
All these things were minor items, but maybe the knowledge will help you on your trip. :)
