Question about the military discount. My sister works for the gov and has a military designation she said although she wouldn't be classified as military but is DOD

. She wants me to plan a trip for her, her son, DIL, and 2 grandchildren. I didn't know about the military discounts. If I were to call in and inquire about this will she get the 40% off on DVC? She really wants to stay there. I didn't know about this. Thanks for any info. What would I need from her to check the rate for her? She doesn't have time to do it and I told her I would do all the planning for her.
