October can be difficult less than seven months out. And even before then. Especially at BCV, BWV which are walking distance to Epcot where Food & Wine Festival is going on.
Remember you don't get daily full cleaning. If you stay seven nights or less, you will get your trash removed and towels replaced on day four (day one is check in day). If you stay eight nights or more, you will get a full cleaning on day four and trash and towel service on day eight. You can't just ask for extra towels or linens or supplies. There is a charge for any extras. And DVC resorts do not offer cots or rollaways. You are limited to the number of sleeping spaces in the villa. (No matter if all your five kids do like sleeping together in one queen sized sleeper sofa

)
So if you like coming back to a cleaned up villa every day, you'll have to pay extra for that. Add that cost into the cost of the "rental" and the 35% discount may work out better. Plus if Disney is offering
free dining or any specials, like buy four get two free or kids eat free or stay and play free, you won't get any of those.
