Be very careful about cancellation deadlines and penalties. Some hotels in Colorado (there's a thread about this for a StR, but lower category properties in resort locations might try to do the same) have a 90 day cancellation deadline for part of the year and if you don't cancel an award stay by then, you will be charged the rack rate for the entire length of your reservation, even if you show up the following day because your flight was delayed, perhaps due to weather in Colorado.
