Just wanted to add a review of our room! We stayed three nights in a HA 1-bedroom, 1526. Somehow we keep getting put in HA rooms even though we do not require them. Anyway, the room was clean and well-appointed. Everything was about the same as a non-HA 1-bedroom except for the bathroom layout. It had a tub/shower combo in place of the walk-in shower and no soaking tub. The bedroom closet was also accessed through the bathroom as opposed to the bedroom, which kind of squashed our plans to put my son's pack n play in the closet (he did great regardless). I believe the bed in the bedroom is lower (it doesn't fit suitcases underneath) but the Murphy bed in the living room was standard. The room itself is just off the main vestibule on the fifth floor of the Villas building, and there was a towel cart outside our door the whole time.
I don't have a lot of other details, just wanted to share this brief overview for posterity and in case anyone wants some info on this room in the future!
