I don’t the exact amount of the discount I got on a garden cottage CL room at BWI, and I don’t remember the exact price but it was high $300’s for a room that was going for around $1k. I stopped calculating the discount when I got to 50% off and it still wasn’t what I had gotten off per night. Some people had around 70% off, it was crazy. Disney let you keep it as long as you didn’t try to modify, which is how I ended up doing a split stay since I dared not touch it when I extended my stay by 3 nights.
