Room request options in online checkin are so ridiculous that I think you should ignore it. For instance, at Kidani you can request “near elevator,” but because there are four sets of elevators, every room in the building is “near elevator”!
The above might apply to certain deluxe resorts, not the DVC side, where a party of two wants two beds as opposed to a king. I’ve read posts on the Disney Resorts forum from people concerned about that.
I haven’t read anything about OKW studios not having two queen beds, so I think this is another example of online checkin requests being irrelevant to the resort.
