After experiencing a drop in international tourists last winter, Alberta’s mountain resorts are banding together on an aggressive campaign to lure Europeans back to the slopes. Owners of the major Rocky Mountain ski resorts travelled to England in spring to meet with more than 40 top European tour operators, travel agents and travel wholesalers to help them design the most attractive vacation packages possible, said Crosbie Cotton, spokesman for the National Park Ski Area Association, which represents ski resorts in Banff and Jasper national parks.
