Party starts at 9 pm (get there about 15 minutes early to check in). Party runs until 10:30 pm. 90 minutes, not 25 minutes, unless they're going to completely change it again. Call back and ask a different CM.
We thought it was wonderful; a whole new way to experience the parade (you can pretty much see all the floats in the 9 pm parade) as well as the fireworks. And Tink literally flies right in over your head!
