I used the planner and the CM for my "Magical Gathering" in May. My planner worked better than anything else!! Everytime I called, they had always lost the MG number, had to transfer my call the correct Dept. then would inform me that my party of 9 was too small and group dinning was for party's of 13 or more. Every time I would tell them my MG number, and that there where 9 of us! Made me nuts, then, the best part was, when I finally gave up, called to make my PS on my own and not go through MG, they would always tell me how great it was and how I should really consider going through them! uhhhhhhh NO! I will say it's just easier to do your own planning and just request things as you need them, such as make your PS through regular dinning, your resort rooms just ask them to be in the same building or whatever!
Oh as far as the planner, I got it to work but no one in my group participated except my daughter and my husband!
