Bring a ski with a 90-100 waist, the groomers and park will be ridden much more than the pow.
We tend not to get storms anything like CO and the rest of North America.
If you get friendly with a ski shop (no homo) in your town then they'll happily let you borrow some wideboys for the deep days.
Apart from that, it's really up to you. this seasons Seth, ARV, Big troubles, MSP, Tahoe?, Anthem, Blend, Kung Fujas (very nice and light).
That's what I'd recommend.
