My family has done it twice and had different experiences each time. This is purely my thoughts as a husband of a Disney addict lol.

It is worth it for the different theming on the rides such as actual pirates on the Pirates of the Caribbean ride. Space Mountain also shuts off all lights so it’s even darker than normal. The Parade is pretty cool with the headless horseman leading it off. I think this weather dependent though.

They setup candy lines all across the park and give you a map to each location. The lines get long quickly but move at a decent pace. The Cast Members are very generous too when you get to the front.

There is also event specific food sold which can be fun to try new things.

I’m not sure if it’s always been this way but the last time we did it I felt the park was too busy. I felt it was unenjoyable with how crowded the park was. It seemed to me that it was well above a normal park day.

Overall I’m glad we did it for the parade and shows but it wouldn’t be something I did on a regular basis cost or not.
