This is something I'm noticing and it's very interesting - FW pricing is currently based on 2020
points charts even though 2021 is out, so depending on your week you could be buying at an immediate nice discount.
I can help here because we own a runDisney FW for Wine and Dine. Our week is week 44, which this year is Sunday, November 1 through Sunday, November 8. The races are November 5 - 8 this year.
The really nice thing about runDisney FWs is they don't operate like a typical FW. For all other FWs, your week is your week - you check in Sunday, you check out the following Sunday. Done. It operates like a typical timeshare week. However, runDisney FWs work differently. They are assigned a traditional FW that corresponds to the usual race weekend (which is why we have week 44), but they flat. MS will call you a week or two before the 11 month window opens and ask which check-in and check-out dates you want. They will ensure your week always encompasses the runDisney event as long as it continues to go on - so if for some reason the race moves to the third weekend in November, they will adjust your week. Also, you don't have to do Sunday through Sunday. We prefer to check out the Monday after the race (so we don't have to travel home the day of the half marathon), so we do Monday through Monday. Or you could even check-in on Thursday expo day and check out the following Thursday.
The one caveat is if the runDisney race is ever cancelled, your week reverts to a traditional FW and you no longer have the flexibility to float the week or days. So for Wine and Dine, that would revert to week 44. For us that was fine because we always go in the fall for Food & Wine anyway.
Also - runDisney FWs are
not available at Riviera, only CCV. Our guide told us they simply weren't popular enough to make a part of Riviera, and as far as I'm aware they were not offered for PVB or any other resorts, so they are unique to CCV.
