In my experience with October trips there seem to be a lot of conventions that reserve blocks of rooms. We have had three trips in October where there was literally no availability at any of the resorts except for the most expensive suites, so we made plans to just stay elsewhere. But then sometimes as late as a week before our departure date, suddenly there was availability everywhere - from Values to Deluxe. I kept checking every day and like Magic, a week or two before our departure date, TONS of availability. I am guessing the resorts released any blocked rooms that hadn't been sold at that point.
