pseudoswede: Thank you very much for the very detailed info!
I don't think I'll want to drive. I'd be nervous to drive on snow.
Keystone's terrain looks awesome, and I like the fact that you say it's family-friendly. The wind thing at Breckenridge is a concern. I do wish there was a Hilton at Keystone that's <5min walk to the lift, though.
Lots to think about.
