In all fairness, OP didn’t say they were looking to buy a DVC. Could be looking to rent. OP could also have points and just looking to spend. A lot of it depends on personal preference. We don't know if it's for a single nights, week long stays, or even if they're looking for WDW only. The more flexibility the more availability and it's amazing how much flexibility there is when you're a single college kid or a retired empty nester.
Just as an example in October WDW, which is pretty much a peak time of year there's currently the following availability.
Oct 1-2 @ SSR & OKW
Oct 1-3, 15-16 @ BLT 1 BR Lake
OCt 6-10 @ SSR Treehouse
Oct 15-16, AKV 2 BR, LT 1 BR Standard
Oct 21-23 @ AKV 2 BR
Oct 28-29 @ AKV Savanna
Oct 28-31 @ OKW 2 BR
Oct 29-30 @ SSR & OKW, AKV 2 BR
Oct 30 - PVB Standard
There's some 5 day/4 night trips that fit in there and multiple 3 day/2 night trips, that's enough to travel on with less than a month's notice.
