We will be flying into Calgary on August 30, staying for one night, renting a car, and driving to Canmore. Can someone tell me if there is a hotel with airport shuttle service near the car rental agencies downtown. I've heard that it is much cheaper to rent the car away from the airport. We would probably not get the car until the following day. Then how to get back to the airport on the return trip? Thanks for anyone's help. This all seems complicated.
