We're traveling into Glacier Park (US) by Amtrak. I've then found a way via shuttle, across the border, then to Waterton Lakes, but I need to find a way to get to Calgary so we can rent a car. From there, we're planning to drive to Banff, then on to Jasper, before catching VIA to Vancouver. Can you suggest any improvements on this plan -- or how to get to Calgary ? Thanks!
