While you probably won't go wrong anywhere there, here's my suggestion: Go to Brighton, ask to speak with Mary (Ski School Director), Chris (Assistant Director), or Carolyn (Ski School training director). Tell them you're part of EpicSki, and I'll be they'll set you up very well!
Brighton is where we held the first EpicSki Academy, just over a month ago. It turned out to be an excellent ski area, with a great variety of terrain. While there wasn't as much snow then as now, they still had some very good skiing. It must be great now. And they treated us very well there.
At Snowbird, ask for Maggie Loring, another occasional EpicSki poster, and the highly respected director of the Snowbird Ski School. Tell her EpicSki sent you, and I'll bet you get great treatment!
You didn't mention Deer Valley, but regular EpicSki contributor and EpicSki Academy coach "Ydnar" works there as an instructor and trainer.
