Replying to Spring Break Plans

Well my parents are starting to already plan for our annual ski trip for spring break. They suggested we go to Whistler, but i've heard that it gets pretty slushy up there in March. Is this true?

If it is what other mountains are great for out west? My parents like a mountain with a great village, Good terrain parks, and of course steep and awesome terrain. Ive already been to Beaver Creek, Copper, Vail, Keystone, and Breck.
I was thinking for other suggestions, to head back to Keystone or maybe Telluride.

What are your guy's experiences and opinions?
