We've stayed at OKW twice in a studio unit, renting points from a DVC member and only paying $80 per night (weekdays). Although OKW is not as intensely themed as some other resorts such as Animal Kingdom Lodge, it is a beautiful resort and the lush landscaping and building architecture do allow you to feel as though you are vacationing in Key West or another tropical location.
Both times we visited we had a first floor unit in bldgs 62 or 64. The foilage was quite dense so we didn't really have much of a view off the small patio. The second or third floors would be much better if a view was important. I was really impressed with the size of the room. We usually stay in a value resort so having the two queen beds with plenty of room to walk around was very luxurious for us. And the bathroom - can you say spacious? The kitchenette area was also great for fixing a quick breakfast in the mornings.
As others have mentioned, the bus service takes awhile to make all the stops within this sprawling resort, and our stop (Hospitality House) returning from the parks was the last one. It might have been faster to get off at the first bus stop and walk back to our building.
We bought some snacks and souvenirs at the general store but never ate at Olivia's. On our last morning we picked up some breakfast sandwiches at Goods to Go, but the service was not very good. The two women working there were almost surly and not at all helpful. This was unexpected, as we've never run into this type of service at any Disney resort or park. Maybe it was the early morning hour and the fact that the ladies hadn't had their coffee yet that made them less than hospitable.
We usually visit in December or January and don't have kids with us so we haven't tried the pool or games or video rentals, but in November 2008 we have a big family trip planned and we've already reserved a 2-bedroom unit at OKW for all of us. It's very convenient to park right outside your building to unload suitcases or hop in the car if you want to drive somewhere. We're also looking forward to having a washer and dryer in the unit - makes packing those suitcases so much easier and lighter.
We are really excited about our upcoming trip and sharing OKW with our family, none of whom have visited WDW before.
