We tried but were not able to get it. Originally DW was able to get CR Tower Club under a travel employee discount but when she lost her job we scrambled to find a new room under one of the discounts available for our time period. I finally called Disney and after a lot of time (literally hours on the phone talking to several managers) they gave us a different discount on the Tower Club reservation we already had. They told us that Tower Club is rarely discounted because it is so popular and there are so few rooms.
That said, I would try and keep trying. You never know what you will find. I got so many different stories from different CMs. Good luck.
