Cons: I arranged to collect the car at 9am, at 8:59 the Banff Avis office called me unfortunately I missed the call as I was on the way to the office to collect the car. When I arrived the customer agent advised there were no cars available until 11am. I advised her I had booked the car for 9am however the agent advised she called me to change the time at 8:3am. When I checked my phone the call was missed at 8:59, 1 minute before collection. This took 2 hours of our car driving through Banff National Park and we couldn't do this when it had got dark after 6pm.
Cons: Their credit card machine was down... so they took an imprint of my card, left my yellow carbon copy in the car and when i called to make sure they destroyed it, no one answered, have yet to get a call back. Also left a small gift from a local giftshop in the back (just a magnet, touristy stuff, and have yet to hear back from the rental car place)... did not have enough people working for such a touristy place.
