It's startling to realize just how much money can be saved at hotels and resorts by booking during periods of low demand. At resorts, that means midweek in the off-season. For example, three nights in a junior suite at Mountain Lodge at Telluride (mountainlodgetelluride.com), costs $837 per adult over a typical weekend during ski season (when booking at least 10 rooms). Midweek during the summer -- a beautiful time to be in the Colorado mountains -- that rate falls to $387. The property also offers discounts on F&B and meeting-room rental during the summer, but not the winter. Check with your hotel contacts to find best seasons and dates for optimal savings.
