We did this yesterday for the first time.
Arrived at the gates at 720. I was initially shocked at the amount of people waiting and was very nervous that it was going to be too crowded. They let us in right at 745 and again I was shocked to see a crowded Main Street. We walked to fantasyland and were routed around the right of the castle by tea cups. Initial plan was to hit PP but it was 757 by the time we passed 7DMT and it had a posted 10 min wait so we hopped in line. It was only a 5 minute wait. We then headed to PP since 7DMT was showing 20 mins. We did PP twice as a walk on. Then we headed back to 7DMT as it had a posted 15. Actual was 10. We then did Winnie the Pooh as a walk on. Then half our party went and met both sets of princesses and the other half rode 7DMT 3 times as a walk on. It was then 9 and we cleared the rest of Fantasy land pretty much and went to breakfast at 945. Breakfast was ok. Plenty of food but the quality is not great.
I felt that the crowds were just right. However, after paying $70 pp I just don’t feel it was worth it. If you only have one day at MK I could see the value. For us it’s a one and done and I’m glad we did it, but I couldn’t see us ponying up for it again. Thanks to all on here for the tips and reviews.
ETA: It seemed most of the crowds we witnessed while waiting at the gate and in Main Street were PPO breakfast people. I think it would help the event if EMM people were let in at 730 and then held at fantasy land until 745.
