We tend to be 1 BR people, which tends to be the worst way to use
DVC from a points standpoint, we don't care. We don't want a studio, and right now don't want a 2 BR.
Anyways, using a potential visit in late May/early June at VGF:
236 Points for 6 nights at VGF
Owning we bought during the "fire sale" and have some resale points as well, estimating our all in cost (initial buy in and dues) around $12/pp the cost for that trip is $2832. If I consider my initial buy in as a lost cost, the cost gets even more attractive, probably closer to $1800 or so....
Renting for that trip would probably be closer to $20/pp which would come out to $4720
Picking a week with cash availability on WDW website (not always easy to find cash inventory for DVC villas) would probably run about $5400 after a discount rate including tax, etc. We qualify for AP and DVC discounts, among others, so we are always likely to get a good deal.
So, I personally would choose to buy as an owner or pay cash through Disney. I would consider renting/transferring points if it made sense to "top off" my membership, add 1 night, etc. and keep in mind it may be easier to rent sometimes than pay for cash inventory - especially for the larger villa units.
We do several trips to Orlando each year.... We tend to do at least one at the Grand Floridian, a few at the Swan and Dolphin, and 1-2 at the Hyatt Regency. Some are longer trips and some are just one night. My personal view is the best way to use DVC is short nights in studios or longer term trips in large units - usually 2 BRs. We tend not to use our membership in that way, but I can't argue with the math of it...
