I have not been able to book a week anytime during the ski season, even though I own there. Too many people just let Valdora rent out there week to pay the maintenance fee, and Valdora gets the rest. I wish I hadn't bought there. So not only are you competing with the many people who own there, you're also competing with Valdora itself.
That's impossible. If you own a ski week you are guaranteed a ski week as long as you book in the 10, 11, or 12 month window. Once the 9 month window opens you likely won't get anything. But the units are sold based on weeks. So if there are 100 units and 10 ski weeks (just an example for math purposes) then there are 1,000 ski weeks for the 1,000 owners. As long as those 1,000 owners grab their week before the open season window opens then they all are guaranteed a week. What you're saying is there are 1,000 ski weeks and more than 1,000 owners or that Valdoro somehow stole your week and sells it and leaves you outside in the snow without one of their plush robes. That's not possible. You might not get the ski week you want, but that's different then not getting a ski week at all which was your complaint.

Are you on-line at 12:01 EST when the calendar turns from 366 days out to 365 days out? That's how you have to do it in cases like this even if it costs you some beauty sleep.
