We stayed in a BWV accessible GV and in an AKV Jambo accessible 1BR (club level). The GV had a roll in shower in two bathrooms and they had permanent shower seats, low light switches, a microwave on the countertop instead of above the range, lower countertops and a chair fit under the bathroom sinks and kitchen sink. The controls on the range were in the front, rather than in the back of the unit.
The 1BR was quite spacious with chair fits under both bathroom and kitchen sinks. Counters were lower. I didn’t take notice of the light switches. The bathroom had the usual grab bars but there wasn’t a roll in shower. It had a regular tub/shower combo with a removable shower wand.
So, it really isn’t consistent from one to the next.
