I was sort of shocked to see that the SR Aspen has SPG C&P availability during the peak ski season when their room rates frequently exceed $750. Most weekdays and several weekends (including Valentine's Day weekend) are available. Some but not all dates require a minimum stay of 2 or 3 nights.

8K Starpoints + $150 per night. Due to a strict cancellation policy of over 30 days advance notice, these are probably all non-refundable for this season.

C&P availability may be found on about half of all days in 2011 through Dec 15. (Hardly any days in April - June, though.)
