Just back from Pop and have some info . I was in one of the disability rooms with the roll in shower. I don't know if the drains are the same in the other rooms but in this room the sink drain did not have a built in stopper. It is just a flat drain with holes with no way to plug the sink so that the water fills it. I use a cpap that should be rinsed in the sink periodically and also I usually like to wash small articles of clothing in the sink. I called housekeeping a few times and the front desk. The response from then was that they would send someone to fix the sink. I finally got them to understand that the sink didn't need fixing... just a flat rubber stopper. But they never were able to find one to put in the room. So just a heads up if you need to wash things out in the sink of one of those rooms bring a flat piece of rubber to plug up the sink or your out of luck.
