We went to our first MNSSHP a couple of years ago and loved it! We got there so we could get in the gate at 4:00. We were dressed like characters from Toy Story, so we made our way to have our picture with Buzz Lightyear. We wanted to do this before the party started.
Tip for watching the parade: We sat on the porch of the Frontierland Trading Post (gift shop). We got there early and a few of us guarded our spot while the rest of us used the "secret" passageway to Adventureland and got Dole Whips for everybody. The Dapper Dans came before the parade and stopped right in front of us and performed. During the party, they are all zombied up and was it great to hear them sing Grim Grinning Ghosts. I think they are technically called Cadaver Dans during the party. It was a treat to hear them. It is a great place to see the parade. My family is kind of over watching the parades, but we all loved this one and want to go back again to see it!
We didn't wait in any character meet and greets, but it was fun walking by and seeing them in their "Halloween" costumes.
We rode rides and enjoyed the shorter lines.
Some of our party watched the castle show and loved it!
The QS restaurants seemed packed the night we went...so we just enjoyed snacks!
Dressing up was a lot of fun! We didn't do anything too elaborate, but it was fun to see others dressed up and also when they told us they liked our costumes!
I know you will have a great time!
