It was a good party last night. I wanted to share my experience. This thread was very helpful in planning my night. There was so much entertainment, plus rides, that I didn't do everything I wanted to see and ride. There were a few special moments.
Two of the rewarding things about this party were that guests were nicer than typical MK crowds. People were in a friendly party mood and I didn't see any fights, bickering, line cutting, or shrieking kids all night. The character entertainers were excellent. I saw the Pooh characters and they put on a great show, as did the princesses. Disney continues to hire and train excellent actors.
I had a 6:40 reservation at GF Cafe. Thanks to outstanding service I was done with dinner and inside the ticket gate by 7:30. It was a madhouse at the entrance but really not a very long wait. I had no idea there was an emergency in the MK. By 7:34 I had my bracelet. Disney's app was still showing many long lines so I did Monster Laugh Floor (which I had never seen), and when it was over I walked onto the Winnie the Pooh and the Little Mermaid rides. By then it was 8:30, so I'd only accomplished 3 rides in an hour. I did stop and watch some fireworks along the way.
Next I rode Haunted Mansion and Pirates as a walk-on. Stopped at Pecos Bill's for a cookie and hot chocolate. No line, super-friendly service. Generally all night, I found short or zero lines for snacks and drinks. I moved over to Big Thunder and it was again a walk-on. I was at the back of the train which is a wild ride, and scarier after dark. I did see some fireworks while I was on Big Thunder.
I went across to Splash and rode with no line. Then I went to Crystal Palace and watched the entertaining Pooh and Tigger, followed by Eeyore and Piglet. These characters put on a nice extemporaneous show and posed for photos. I wish Disney was doing more of these shows with more characters.
From there to Buzz--again no line, then watched the dance party with Stitch and drank a big coffee. Back to Fantasyland and Peter Pan with no line. It was nearly midnight when I went to Seven Dwarves Mine Train. There was a short line, maybe 10 minutes. I was in the second seat, and a very brave woman was in front of me with her arms up the entire ride. I hung on for dear life. It was my second time riding it, and I didn't get motion sick, so I'll try it again one day.
Time to get the Jingle Cruise. This was disappointing. The line was about 25 minutes (Disney said 50) and it just wasn't very entertaining. I should have skipped it. I went back to Fantasyland to meet princesses. They were great, they helped me record a video Christmas greeting for a friend. With time running out, I rode the People Mover as it turned 1am, and it was time to go. Boat back to Grand Floridian, then drove home to my resort. I was back by 2am and very tired. I walked about 8.5 miles.
What I missed: both parades, the stage show, and some fireworks. I also wanted to meet Santa and Mickey but didn't have time.
Summary: guests well-behaved, cast members top-notch, more than enough entertainment. Non-existent lines for most rides. I think it was worth the money.
