We will be stopping in Calgary en route back to Vancouver after driving through the Rockies.We will be coming in from Banff and will drop the car off at the airport prior to departure. The question??? is it worth spending two nights in Calgary as opposed to an extra night somewhere else in the Rockies, We will want to do some shopping and may consider going to the museum,I know the Zoo and a few other things are highlighted but they get mixed reviews. Trip is end of July with teenage girls who will certainly want to go to at least one mall. Question is also where would we stay, downtown though most things look as if they close after the offices close or near the airport, assume prenium parking costs with car downtown or cheaper airport araaccomodation. Read somewhere about a free train ??
