We've rented last minute
DVC 2-bedroom villas (and even a 3 BR) over the past several years. We are local and have full flexibility in our schedules to wait until there is a distressed renter that drops the price usually a few days before. As such, it has provided us wonderful opportunities to get an otherwise much more costly DVC villa.
The being said:
The 2 BR can offer much larger and connected balconies (i.e. VGF and AKL-Kidani). This provides extra space for socializing and breathtaking views (and morning coffee). The 2 BR offer washer and dryers. But, OKW offers a full-size washer and dryer in its own room and not behind a bifold door. OKW 2 BR villas are massive, and we always stay along the canal to have a great view.
We fully take advantage of the kitchens and cooking some meals in the villas. It saves quite a bit of money, but more importantly time. It is also ultra convenient when you want something within arm's reach when watching television/movies.
My personal preference on 2 BR villas (in order from top to bottom):
OKW (only with canal view. OKW's boat to DS is fantastic and their quiet pools/hot tubs are wonderful)
VGF (glorious architecture and theming)
AKL-Kidani (only savannah view and has a 3rd bathroom)
SSR - only if near or at Congress Park (a simple walk to DS or even the adjacent boat dock offers some good dining options at POR/POFQ.
SSR Treehouse - this has the best location with basically a private dock and ultra quiet pool, but it misses the mark with outdated rooms. But it offers plenty of space and privacy in the woods or along the river. If these get a proper refresh, it could be our favorite.
Hope this helps a little.
