I personally love the WL/WLV area: It's so peaceful, quiet, and truly makes you feel as if your in the Northwest...
With that being said though, the villas aren't my favorate. The room decor is what really turns me off. The decor mimics my grandma's old cabin in NH, old and outdated. Which, don't get me wrong, is very fitting for that resort, but not nearly what I would expect from a "resort" timeshare... especially now comparing it to the WL renovated rooms. To me personally, it's very distasteful and un-deluxe like. I did not get this feeling with any of those other DVCs (with exception to the "worn" look over at OKW, but those 2bedrooms are HUGE!)
Factoring out the decor, the rest of the resort rates top notch! The grounds are fantastic, area is nice and quiet, and you can get a decent view from every room. The villa pool is nice, but your a few steps away from the WL resort and there amentities. I like having roaring folks, WWC and AP on property as well as the Marina and ability to watch the water pagent. The boat dock is a little bit of a walk from the Villas, but the surrounding grounds makes it an enjoyable one.
I do consider a move from the BWV to the WLV to be a bit of a "downgrade"... but it really depends on what you prefer.
