I do know that 5010 is a full accessible studio, we stayed in it in June, so I would assume 5011, the connecting 1 bedroom, is also a fully modified unit.
The studio had a roll in shower, no cupboard space in the bathroom, raised commode, modified closet and a lowered kitchenette. The beds were still "high" though. I don't think I've seen any OKW units with lowered beds.
Some HC units are ony partially modified, so Scot is correct, if you need a specialized unit, call Member Services nd ask to be transferred to the WDW Special Needs person.
