As mentioned above, home resort is only important regarding booking. You can book at 11 months out at your home resort or 7 months out anywhere. Booking in the 11 month window is absolutely essential if you are traveling during
DVC peak periods,
and you really care where you stay, but we've had excellent results booking at <7 months during non-peak times.
Home resort is obviously
only important if you can usually book more than seven months in advance. If you can't, what's the point?
If you are unable to book more than seven months in advance, or you don't really care that much where you stay (our situation), you may want to consider other factors like initial buyin price or maintenance fees. For us, the financial aspects of the purchase were more important than home resort...but every family is different.
For a couple with no kids, BWV or BCV would be a great location because of the proximity to Epcot and Disney Hollywood Studios, as well as the nightlife at the Boardwalk...if that is what you are looking for.
But it's not a great location for MK or AK or the water parks. If you are bussing, you'll hear more complaints about the buses from the Epcot resorts than any others. And if you're driving, I can get in my car at OKW and be at MK before the valet delivers your car to you at BWV or BCV.
As far as accommodations, I agree with previous comments that it's a matter of preference with studios. For you and DH, you might like the queen/couch combo; for a two-girl trip, you might find the two queen beds at OKW more comfortable.
(I will say, though, that the sleeper couches in every resort I've stayed at are
very uncomfortable to
sit on. They're nice visually, but they're miserable furniture.)
For one bedrooms, I don't think there is anything to compare with OKW. An OKW one-bedroom has
much more space (about 40% more than some resorts), plus a full washer and dryer instead of the stacked pair, and a larger jacuzzi than some other resorts. We stayed a couple of weeks ago in a one-bedroom at SSR, and it was really chopped up, and awkward to get around in.
Having said that, OKW is a big resort and you shouldn't need home resort advantage to get in there except during peak times.
