We aren’t going to have a park hopper and are wondering if Hollywood Studios is worth spending the day at or if we should just repeat one of the other parks like animal kingdom. It doesn’t look like it has a lot to do.
Hi, Coolp, and welcome to the DIS. This question might be better asked on the Theme Parks board, but I 'll share my opinion.
It does depend on what you are interested in and Hollywood is a bit show heavy, but with Toy Story Land now open there really is plenty to do. HS is home to some of the coolest rides, like the Tower of Terror and Rock'n Roller Coaster. If you have Star Wars fans, then it might be a must do for Star Tours and the Galactic Spectacular. Fantasmic! is a great show too. Some of the shows are longer and do take up more time.
To run it down, here is what HS has to offer currently:
RIDES:
Tower of Terror
Rock'n Roller Coaster
Star Tours
Slinky Dog Dash
Alien Swirling Saucers
Toy Story Mania - How'd I miss that?
SHOWS:
Indiana Jones Stunt Spectacular
Muppet-Vision 3-D
Frozen Sing Along
Voyage of the Little Mermaid
Beauty and the Beast Stage Show
Walt Disney Presents (small museum with a movie about Walt Disney or movie preview)
Jedi Training Academy (kids can participate if they want)
Coming Soon: Lightning McQueen's Racing Academy - I'm not sure when this will open or when you are going but it will be an "interactive show").
NIGHTITME SPECTACULARS:
Fantasmic!
Star Wars: A Galactic Spectacular (paired with Disney Movie Magic projection show)
Only you can decide if that is worth it, but generally I think it has a lot to offer. You'll have fun either way.
