I went this last September for 2 weeks for my honeymoon towards the end of the month. We stayed at the POR and wanted to extend our stay by a day or two and when we went to the front desk to see about it they said there wasn't a single room available so we could extend just one more night! We had them check all the moderate and all the value resorts and there was not a single room! This was the first night of the food and wine festival and we were told that's why they were at capacity. But if they can get to capacity in all moderate and value resorts in late September, early October (value season), I don't see how they'd have a problem filling rooms during peak season.
Just seems odd to me. Of course, there could have been some conventions or other events in as well during our stay that caused them to reach capacity.
