I've observed that CR discounts are often lower than others, but it was included in this last offer released 8/1. It wasn't listed on Disney's website, I think, because it was only 20%, so it didn't fit into the pretty display. They were saying 30% off deluxe, and 20% of mods, so the 20% couldn't be listed anywhere without extra fine print.
But, when I called, there it was, mine for the taking.
I think during the planning phases, it's most important to plan the vacation you are happy to pay for. Any discounts are nice bits of magic, but nothing to count on. So, if you are happy to pay rack rates at CR, then go forward with that. If you are banking on a discount and will feel irritated if CR isn't included, then either plan once the discounts have been released, or find a resort that you wouldn't mind paying rack rate for.
