Sending thoughts for you! Hugs and pixie dust.
As for
MNSSHP suggestions,
1.) Either eat early or snack like you plan to. We did Liberty Tree Inn at 4pm and it was perfect to get us through the party. Nice and filling, then we were hungry and enjoyed our pumpkin waffles with ice cream at about 9pm. I honestly can't remember seeing any restaurants closed. I know a decade or so ago they used to close some of the CS locations to be Hot chocolate/Cookie stations. *Shrugs*
2.) Villians show was awesome.. And if you have a desire to meet any of those villains that rarely show, get a good seat up front. They come down to the front of the stage at the end of the show for pictures and autographs. Wicked queen, malifaceint, the voodoo man, frollo from hunchback, cruella, etc.
3.) I did not watch the castle show. My mom and Ann said it was neat, but I got a coveted meet and greet with Jack Skellington and Sally after only about a 10 minute wait at it was a nice long interaction with a video taken of Jack saying he couldn't wait for my DF to come meet him. It was awesome.
4.) we went on a Sunday night and didn't feel the crowds were bad. Lots of candy trails. Very spread out and almost a walk through line.
5.) Be in line for the Dwarves when the line starts if you want that picture. We ate then went and got in line. Yes we waited about 45 minutes, but the park was still full of non party goers. So we were like the 10th picture with the Dwarves, we were done about 20,minutes after the party had officially started! It was fantastic!
6.) if you are going to dress up, my suggestion to you and since you have semi adult children. Search Disney inspired outfits or Polymore or Pintrist. Our outfits turned out cute, they were things we could wear after Disney, and we were comfortable... Except for Ann's hair. (Pics are on my PTR if you wanna see.) They were a hit too. Everyone loved Ann's Ariel. The dwarves freaked out of my Snow White.
7.) The parade is not to miss! It is just so different and neat. So many costumes, and characters you don't normally see. The guys from haunted mansion dancing with the shovels and making sparks was probably my favorite part.
8.) HM line was almost a walk on. But if you have a moment, for sure listen to the southern bell ghost sitting outside on her bench. We was a hoot!
Over all, we loved MNSSHP! My mom felt like we wasted money all those years ago doing
MVMCP, she thought the Halloween party was well worth the money spent!
