Whitecap Mountain is the BEST ski resort in the Midwest. I've taken my ski club there three years in a row, and the first year I had a hard time getting people to sign up because no one had heard of it. But when we returned and people heard about the skiing, the next year I had considerably more and the last year I carried a full bus.
Whitecap is a real fooler, and since they don't advertise it's never crowded. Once you take the lift up the front face, ski down the backside and you're in "ski heaven". At first glance you think you're out west and you'll really need your trail map (although most trails are not visibly marked, you just have to guess). Also, take time to visit the "Winehut" for an Apple Pie (Rum and apple juice)and definitely plan ahead when it's time to go back to your lodging because it will take a while to find your way back to the front of the mountain (usually 2-3 extra rides up the lift before finding the right trail back).
The accommodations at the Lodge are a bit rustic, but clean and do-able. For better accommodations try there villas and townhouses, most ski-in/ski-out and have kitchen facilities so you can cook for yourself because the restaurant does leave you wanting. Dollar for dollar, Whitecap is the best value for top flight skiing in the Midwest.
