As many others have posted, OKW has the largest units out of all the
DVC resorts, it is very quiet and you can park in the parking lots located in front of every building. For a non WDW lover like your DH, OKW might be just the ticket since you will be removed from the parks and the hustle and bustle associated with the parks and the MK and Epcot resorts. Think of a nice condo development surrounded by a golf course and that pretty much describes OKW.
I have experienced less than the greatest transportation while staying at OKW when relying on buses and would not stay there again without a car. I have had much better bus transportation from the value and moderate resorts. If you are going to be spending a lot of time at Epcot, OKW is definitely not the most convenient place to be staying at for quick trips to Epcot.
I am sure you will have a great trip and will get to experience a new place. Like all the Disney resorts, OKW has it's fans and also has those who do not care for the location, extremely quiet atmosphere, lack of amenities, elevators, etc. It all depends on what you want on vacation. If a large unit, in a quiet atmosphere with parking at the door appeals to you OKW is perfect. If you desire a resort that offers full deluxe resort amenities, the ability to walk to parks, restaurants and nighttime entertainment and you also wish to be in the middle of the action and Disney magic then there are many other WDW resorts that would be a much better fit.
I am like Lisa F, and only stay at OKW if I can not get into any other DVC resort and have in fact canceled trips to WDW when only OKW was available and rebooked for a time when one of the other DVC resorts was available. Matter of fact, I cancelled a WDW trip that would have had me there right now but when I could only get a reservation at OKW, I rebooked. After the particularly bad winter we have had the thought of being in sunny FL right now is very appealing but in the long run I know I will be much happier waiting 2 more months and staying in a DVC resort that I enjoy. Not to put OKW down, but if it was the only DVC resort on WDW property, I would definitely NOT have become a DVC member.
