I heard that although Cirque is on Disney property, strictly speaking it is not a Disney show therefore no discounts, not even to Disney CMs. We're certainly going to to see it in the next couple of weeks - can't wait.
First, welcome to the Dis Boards! I called Disney at 407-939-7719 at 7:00 am Eastern time exactly 180 days from the day we wanted to see Cirque because I wanted the best seats possible. I saw that Ticketmaster.com couldn't begin selling for the day I wanted until a week later. I also did not find any discounts. They did have a 25% discount for AP holders but not for my dates of travel. This will be our first time to see the show so we can hardly wait. Good luck.
