Not sure if you still need the answer or not. But I went on the website and I see what you're talking about. I clicked on Book Room and more specifics showed up. Then I just either selected a different room to see the other descriptions.
Unfortunately I didn't book anything. No way we can afford Disney for a while but I was curious. I didn't think the prices looked the discount was appllied though. Maybe that was further on in the process - I didn't accidently want to book anything so I stopped at that point.
Good Luck.
