The tour company Viator should have informed customers the tour will only take you to Discover Center, not including the glacier ahead of time. There is very limited cell phone signal. Our family of three booked the “Columbia Icefield Tour including the Glacier Skywalk from Calgary” from Viator.com. When we arrived at the pickup location Delta Downtown Hotel, tour guide Mark informed us that the tour includes Discovery Center but not the Glacier. However, he offered no help on how to purchase additional ticket to the Glacier. When we were searching for the ticket to the Glacier on the road, he told us the cell phone signal would go out in few minutes. My family were in a hurry to buy online but were unable to complete transaction before signal went out. When we arrived at the center, he asked us to buy Skywalk ticket only (the ticket was sold in either a combo of Glacier and Skywalk or Skywalk only) because we must return by 3 pm. We were not happy but we listened to him. When we returned to parking lot at 3 pm, we found Mark was looking for a missing guest. The group were not able to leave the parking lot until 5 pm. So, we would have made it back to the group even if we had bought the 3 pm combo ticket. In a hindsight, Mark did not handle it well because he told us that he could skip other attractions such as Bow Lake and Peyto Lake, and directly go to Discovery Center as needed. He explained that the tour could get to the lakes as it returned on the same route. But he did not do so. If the group arrived in the center early, we would have enough time to complete both attractions. Mark offered no assistant in helping us to purchase the tickets either online or at the center is a shame of him. Also he waited until we were already on the road to inform us about cell phone signal being out was his fault because he knew buying ticket requires cell phone service. The company Viator should have emphasized the tour takes guests to Discovery Center ONLY not the Glacier attraction because the title of “Glacier Skywalk” is misleading.
