Discounts for Ft. Wilderness campground?

[t_catt11]

We just booked for 9/18/2020 - 10/4/2020. This will be our first time to do the campground; it just made a lot of financial sense for us, as even a HUGE camper rental came out cheaper than two value rooms (we are two adults, seven kids).

I have seen that eeeeeevery rare now and then, there are small (15%) discounts available for the campgrounds. I'm hoping to see something like that for either the general public or for passholders for at least part of our stay. Not that it's a lot of money, but every little bit helps!
