Best Roll In Shower Room at CBR?

We will be at CBR in August and there will be a total of 9 people in 3 rooms. 1 of our rooms need to be handicap accessible with a roll in shower and we would like the other 2 regular rooms as close possible to our elderly parents.

I looked it up on the room viewer and there are several options so I was wondering if anyone had recommendations on the best rooms to request?
