Disney’s Hollywood Studios’ nighttime spectacular in which you enter Mickey Mouse’s dreams in a show featuring projections, characters on stage, boats, fire, fireworks, and more. If you’ve never seen the Disneyland version, you’re likely to be blown away by Walt Disney World’s Fantasmic, which is completely unlike the fireworks at Epcot and Magic Kingdom.
If you only have one night at Disney’s Hollywood Studios and have to choose between this and Star Wars: A Galactic Spectacular, choose this unless you are a huge Star Wars fan. Fantasmic is significantly better. Depending upon your priorities, Fantasmic can be a good use of FastPass+.
