Some facotrs to include in your evaluations:
1, The end dates for the resorts can be an important factor particularly if you are still young. BWV, VWL, BCV, VB, and HH all end January 2042. OKW, as a result of an option that was made to extend, has contracts that end in 2042 or 2057. The 2042 contracts have only 29 years left and and unless you are currently at least in your late 40s, that can eventually have a real impact. SSR is 2054, AKV 2057, BLT 2060 and VGF 2064 and thus all offer a longer comfort zone.
2. Current reservation patterns may change in the future including because Disney could do something to change them, e.g., move Food & Wine to the Spring or create some other new popular event for some particular time of year, or change seasons for something, e.g. move early December to a higher cost season while moving sometother dates to the lower cost season. Nevertheless, the current patterns can be summed up as follows when it comes to the 7 month reservation window for WDW resorts when you can reserve things other than home resort:
(a) End of Sep through marathon weekend in Jan is by far
DVC's highest demand quarter and during that time it can be difficult to get near park resorts (BWV, BCV, BLT and likely VGF) at 7 mionths out particularly if looking for more than two or three days in a row, and the same for VWL for time beginning near Thanksgiving to early Jan. Nevertheless, wailtlist is an option and many times comes through. Also, 1BRs tend to be the last to go any time of year and those can often be open at 7 months out for near park resorts during that quarter.
(b) During that quarter, AKV (except club level and value), OKW, and SSR are usually open at 7 months out but there are even times during that quarter when AKV and OKW can have some (and I emphasize that it is only some) risk of having some days full by the 7 month window such as time around Columbus Day weekend, the weekend following that, few days at Thanksgiving, first week of Dec and time around NYE, and SSR treehouses around Thanksgiving, first week of Dec and NYE time.
(c) During that quarter there are three easy periods when near park resorts are usually still open: Nov after Veterans day to Monday before Thanksgiving, third week of Dec, and time between Jan 3 and Wed before marathon weekend.
(d) Certain categories of rooms have a risk being gone, not just during that 4th quarter but any time of year, before 7 months out because of their high popularity and limited number: AKV club level and value, BLT standard, BWV boardwalk and standard view, BWV GVs, the OKW GVs in the hospitality house booking category, and at times, like around holidays or some times in June, BCV studios and possibly 2BRs, and BLT theme park studios. Though the evidence is not in yet, that will likely be true for VGF studios The exception is that 1BRs in some of those categories are often open at 7 months out.
(e) Otherwise, the time between the Monday after marathon weekend in Jan to end of Sep (when Food & Wine begins) is a slow to moderate DVC demand season, including any holidays during that time, and near park resorts except for the possible exceptions noted in (d) above are generally easy to get at 7 months out. There is a time during that period that approaches the level of demand of the last quarter and getting a near park resort can be difficult: the weekend in the latter part of Feb when Disney holds the Princess half marathon.
3. Thus, if you regularly want AKV value or club level, BWV standard or boardwalk view, BLT standard, a BWV GV, and likely VGF studios, you would be wise to purchase at the given resort. Moreover, if you regularly want a near park resort during the fourth quarter, you should seriously consider owning at the particular resort. However, if you plan to usually travel between mid-Jan and end of Sep you could easily buy SSR and have a high probability of getting a near park resort at 7 months out, with the caveat the demand patterns could change in the future particularly if Disney does something that could change demand patterns.
