We are planning our 1st visit to the region this year (2012). The primary focus is sight seeing with escorted tours just outside of peak season. What are best times of the year and the recommended Tour Operators. We live in Toronto, so expect we will have to fly in and out of Calgary. Came across caravan.com - any personal experiences to share? Which are the best Tour operators / Tours? We have 10-15 days, so are flexible. Don't mind doing BC as well, but concerned it might be a push. Initially we were thinking of renting a car, but find that escorted tours may be netter value for money.
