OKW is a Disney Vacation Club resort, but all the DVC resorts can also be booked by paying money and not using DVC points. You do not have to be a member to stay there. You can try to reserve by paying cash/credit or you can rent points from a DVC member. If you pay cash, you will get normal maid service. If renting through a DVC member, you only get maid service on your 3rd or 4th day, which I believe is only basic trash service. You do have the option to pay extra to get the full maid service. Hope this helps!
I am staying at OKW for the first time at the end of March. I hear the rooms are very spacious.
