Each year, Starwood Preferred Guest asks their members which properties are their favorites. The program publishes the top 12 properties in eight categories, including Best Beach Resorts, Best Golf Getaways and Best Romantic Retreats. With ski season just around the corner, we checked out the properties members selected for Best Winter Adventures. Members can redeem 12,000-16,000 points for a stay at the Category 5 Westin Monache Resort in Mammoth Lakes, Calif. or the Sheraton Steamboat Resort in Steamboat Springs, Colo., two of the top 12 winter picks.
