I think
MNSSHP is one of the best up-charge offerings that Disney does.
The guests wear costumes and the entertainment is top notch. Go! Concentrate on the parade, the Fireworks, the Hocus Pocus stage show, the Cadaver Dans, Madam Carlotta and friends performing on the lawn of the Haunted Mansion and the character meet and greets and finally the candy. Save the rides for another park day or the times in between your party agenda.
I think that because so many guests participate by wearing costumes the fun is really amplified.
MNSSHP is a not to be missed experience.
