OK, here we go...
I personally love OKW. We are DVC members as well, and OKW is our home resort. I have stayed at all of the DVC resorts with the exception of the one on Hilton Head. We usually stay at OKW if our family is coming along. You get more nights for the same amount of points, which is a plus, and it is nice and quiet, so we can head back to the room mid-day and swim or watch golfers or what ever, and it seems like a different world from the parks. It has a substandard pool area compared to the other resorts.
We usually stay at Boardwalk if it is just the two of us. There are great restaurants within walking distance, as is EPCOT, and Disney-MGM Studios, if you don't mind walking for a while. The night life is great there. The rooms are a little smaller, but not really noticeably so. If you want to be in the center of the action, this is the place to stay. Boardwalk's pool is great, and you can walk over to Beach and Yacht Club's pool, which is out of this world.
Villas at Wilderness lodge is in between Boardwalk and OKW. It is quiet, yet close to Magic Kingdom and the amenities of Wilderness Lodge. I love Wilderness Lodge, and the Villas are just an extension of that same feeling. It is about the same price as boardwalk, and if I were choosing between the two, I would go to boardwalk. The pool there is great though, as are the restaurants.
Probably my favorite of all of the would be Vero Beach. It is only two hours south of the magic. It has its own private beach, great pool, good restaurants and a nice little town just down the road. No theme parks, but a great resort. If you have the points, the three bedroom beach house is fantastic. We were upgraded once from a two bedroom to the beach house, and it was so nice I couldn't believe it.
I would assume that the new Beach Club DVC will be similar in price as boardwalk, but a little more quiet, and closer to EPCOT.
As a summary, I find the quality of the resorts to be similar. When you plan your vacation, I would look at staying at some of the other resorts. If you love EPCOT and the night life of the Boardwalk, try that one time. If you like relaxing outside the parks, OKW and Wilderness Lodge are great. For us, it comes down to price, and we usually get more at OKW than at the other resorts. We can usually go twice a year every other year to OKW and stay in a three bedroom for nearly two weeks, where as if we stayed at Boardwalk we would lose a couple of days. Not saying the others are bad, they are in better locations, so you pay for that. Next time you are in Orlando, go around and check out the other DVC resorts. Swim in the pools, ask to see a room. DVC members can swim in any pool at any resort in WDW, with the possible exception of Animal Kingdom Lodge, depending upon who is at the gate that day.
Oh, and the other resorts at WDW that are not a DVC resort are fantastic. I would rate the moderates (Port Orleans) just below DVC and the Deluxe resorts above. Wilderness Lodge, Polynesian and Animal Kingdom are out of this world resorts. If you are a DVC member, they will give you a pretty good cash discount if you would rather stay there. Don't use your points though, not a good deal.
Good luck, you won't be disappointed with any DVC resort.
