damn, he pretty much summed it up.
If you want the ski vacation experience, it's Northstar.
If you want killer terrain, do Squaw and Alpine. Stay at squaw, take a shuttle to alpine if you want a change of scenery. Seriously, you won't get bored at those two resorts for a while.
If your parents are there and want a lot of entertainment, maybe South Lake at Harrahs. No ski in ski out, but there's a Gondola to Heavenly.
