Excellent info MNSkiing. I like how well you laid all of that out. That's essentially what I did the last two years as well, but I never saved my planning.
I looked at VRBO last night and you can get much better deal on there than booking through the resort IMO. Especially since I have discounted ticket through Welch villiage. Found some nice ski-in ski-out condo options we're looking seriously at booking.
