I spoke today to Kaitlyn with Disney Sports about the substitution of the Happily Ever After Party for the Pirate and Princess Party that was originally offered at a discounted rate with our Princess registration. She said the details are still not complete - but so far the plan is for the party to be held at MGM (sorry - can't call it HS yet) until midnight, with the usual limited attractions open (RnR, ToT, GMR, TSM), a princess meet and greet, and a performance of Beauty and the Beast.
I pointed out to her that it is EMH evening hours at MGM that night. She was surprised and said she would mention that to her boss right away. Hmm. I also pointed out that if you have an annual pass or use your admission ticket elsewhere anytime that day as it stands now you could stay in the park with EMH until 10PM. What would I be getting for 2 extra hours (and spending $40)? She mentioned the possibility of a Princess Parade, but surely that would have to be after the park closes for EMH at 10PM. I suggested a free 5x7 picture with the princesses might be nice (but not worth $40).
I asked her to please make sure they announce the final details before the Feb 20th refund deadline. IF you don't have an AP or have an admission ticket to use that day, you can enter MGM with your Happily Ever After ticket after 4PM, so that still might make it a good deal.
I also suggested that it would be wonderful if they came up with a second half marathon course, and they could alternate it with the Jan half. One year do course A in Jan, and course B in March, the next year to course B in Jan and course A in March. She said she would pass that along.
