Booking your vacation early can get you bigger discounts for skiing the Canadian Rockies resorts this winter. Those booking vacations by Nov. 30 through Ski Big 3 can choose from a ski bag full of offers, including a free day of skiing at Sunshine, Lake Louise, or Norquay - all located in Banff National Park.

Banff Lodging Company, which operates the Inns of Banff, Banff Ptarmigan Inn, Banff Caribou Lodge, and Hidden Ridge Resort, is offering 30 percent off stays when booking four or more nights by Nov. 30. The special is only available for certain room categories and valid to Dec. 22, Jan. 3-Feb. 10, and during March. (Hidden Ridge is not available for March.)

Rates start at $69 per person per day. Prices are based on double occupancy.

All four hotels are located in the town of Banff with bus transportation linking to Sunshine, Lake Louise, and Norquay. Purchasing a minimum four-day tri-area lift ticket valid at Mt. Norquay, Lake Louise, and Sunshine Village also adds a free day of skiing.

Canadian Rocky Mountain Resorts is also offering a fourth night free and a free ski day with a four-day tri-area lift ticket. You can opt to stay closer to the town of Banff at Buffalo Mountain Lodge, in Lake Louise at the Deer Lodge, or in Yoho National Park at the remote Emerald Lake Lodge.

Rates, which are based on double occupancy, start at $85 per person per day. The special is available until Dec. 17 and Jan. 1 to May 24.

Bookings for these special rates must be made by Nov. 30 through Ski Big 3 in Banff.
