Many people (DVC members and Non) love OKW. The theming is very relaxed and lovely and it really has a wonderful Florida feeling about it. One thing about DVC is, even the smallest room (a studio) is far superior to a normal hotel room. Your studio will have 2 queen size beds, a bathroom (I think with only one sink) a kitchenette with a mid-size refridgerator, a sink, cupboards, toaster, microwave, coffee maker, and other things like paper towels, garbage bags, paper plates and bowls and plastic silverware. (also some things like dish soap and and starter coffee.) You will not have a washer or dryer in your room, but have free access to one at the pool.
The one and two bedrooms are much better, lots of room and very comfy. Word of warning, after staying there you will want to look into joining DVC. (we are very happy we did, it is addictive.)
When we compare OKW to other DVC resorts we tend to feel a bit disappointed. IMO it is more like a Mod resort with far superior rooms. It is very spread out, and while we love WDW busses, we were not impressed with OKW ones. It can be difficult walking with small children, espcailly in the rain. If you have a car it is great because parking is close by. If you have a child ask for a room on the 1st floor since most buildings do not have elevtors and getting the stroller up and down the stairs is difficult. (especailly in the rain.) The castmembers are very friendly and most seem to really like their job. There is many pools, but no slide (they are fixing this in the near future.)
One word of warning, where your room is does make a difference. Ours was a studio that was really near the road, and we could hear every bus buzzing by from 7:00 am to 2:00 am. We live near a train and it doesn't bug us, but the busses did.
All in all OKW is a very lovely resort and $160 a night is a great rate. Have a wonderful time.
