I always double check in a follow up phone call to make sure my room is the correct type.
A room location (including potentially Jambo vs Kidani, I am not sure how the DVC booking process works for that) is a *request.* But a HA room is a *requirement.* For example, when I stayed at CSR, I booked a HA room with a roll-in shower. That was guaranteed. I requested to stay in one of the Casita buildings - that was a request and did not have to be honored. I was lucky and did get the building I wanted, but that was not promised.
