Once you know about getting on any bus for travel within the resort, it's very quick and easy to get from your villa to the Hospitality House/main pool/store/Olivia's/quick service and back again. Just have to be sure to mention to driver that you want to get off at the Hospitality House (main building). And when ready to go back to your villa, walk across the street from the HH to the first bus stop and it will circle around the resort.
We love OKW because it's relaxing, rooms are big and cast members have always been great. Balconies in a 1 BR are full size, with a table and 4 chair and a ceiling fan. It's close to Disney Springs (either by boat or walking -- if you're at the end of the property closest to West End). We spend a lot of time on the balcony or at the pool.
Unfortunately, we've never been crazy about the quick service food, but do like Olivia's very much. You can usually get in without a reservation. If you have a car, it's a very quick drive to Saratoga Springs, which has an excellent restaurant and quick service that offers some different options.
If you can do stairs, you may want to request a room on the top floor. Views are usually better and no one is above you. In most buildings, the top floor is the second floor, so it's not a long climb. Many rooms overlook the golf course and some have a 'water view' of the river or a lake. We've stayed there many many times and continue to love to go there, even though it's not where we purchased DVC.
Hope you have a great trip!
