It's been mentioned before that, after AK, this park is not necessarily an all day park. So adding two additional shows--Little Mermaid and Villains--could spread out crowds and the length guests are in the park.
So by my count, HS will have six ongoing shows (five for a while after MV3D closes) during the day to spread out the crowds and keep them longer:
- Beauty and the Beast
- Frozen Sing Along
- Indy Stunt Spectacular
- Little Mermaid
- MuppetVision 3D>Monsters, Inc Show
- Villains
I'm not counting the Mickey short or Fantasmic for this purpose. Obviously, Fantasmic helps for evening touring.
