At the very least with a new section to Contemporary there should more
Handicapped Accessible rooms with roll in showers. As far I know the CR tower only has 1 HA room with a roll in shower and that is located on the 12th floor in the Atrium Club.
It breaks my heart with a fellow DIS'ner posts on the resorts board or disABILITIES board asking where the CR tower HA rooms with roll in showers are located (hoping for a room with a MK view) and I have to reply that there is only 1 room on the club level and that it often booked a year in advance.
