Always a good idea. March is our snoweist month, and most spring breaks aren't til a little later. You'll have lots of fun.
North woods is good early in the day, i ususally make a couple runs there before heading to the backside. Blue sky basin is awesome, there is fun glades skier's left in the china bowl, go along the edge, it doesn't get tracked as fast as everything else. And a day or two after you get snow hit up the mongolia bowls, it's a bitch to get back to everything but the snow will still be good there. Check my pics if you want. The first cliff is above the poma accessing the mongolia bowls, and the other two are lover's leap, blue sky basin.
For breck, hit skier's left of the horseshoe bowl, under the 6 chair is always fun, and good for windy days.
Have a good trip man.
