Hey, Rink -- the year after I bought my maintenance fees DID go down, so it is possible.
Now for the original question, no, it is only "sort of" accurate. The "slow" season
is fairly easy to book. Problem is, the "slow" season for
DVC is NOT the same as the slow season for WDW and its other resorts. Most people think the busy season is summer vacation and the Christmas holidays. For DVC the busy season is:
- Oct 1 through November 15th for Food & Wine. The Epcot resorts book up in a flash, the others WILL sell out with the overflow, they just take a bit longer
- the week of Thanksgiving (usually the week after Food & Wine)
- the week after Thanksgiving, followed by early December (low prices and great decorations), followed by the Holidays, followed by the Marathon (early January). So, essentially everything from Oct 1 thru Jan 10 or so is a pain booking at 7 months or less, at 3 months virtually impossible.
- Spring break, can be as early as late february rising to a peak for Easter and the week after, so now we are talking some years mid-April
- all holidays: MLK, Memorial Day, 4th of July, etc
So that pretty much gives you a limited window of "slow". Slow for DVC is probably late January, some of February (Except for MLK week), late April thru mid May, Very late August through September and a few days between when Food & Wine ends and Thanksgiving week begins.
Summertime - the traditional busy time for WDW - is not as busy for DVC. While I wouldn't call it slow, it's not nearly as sold out as the times I've listed above. I don't know if I would say it "wouldn't be hard" to get a room. Everyone's definition of hard is different - some people think the waitlist is not nerve wracking or don't mind a 7 day vacation where you have to change hotels twice. But, lots of flexibility and creative use of the waitlist would probably get you something.
Frankly, I've made ressies at less than a week out (once in June, once in early Feb), but in general three months (except at very slow times) would be pushing your luck.
