Are you going to see the Rock the Night Fireworks Spectacular tonight at Disney's Hollywood Studios. There's definitely a best place to view them from if you want to enjoy the entire vantage point.
Don't let the name fool you, the Rock the Night Fireworks Spectacular is the same fireworks that Hollywood Studios shot off a few weeks ago for New Years Eve (minus the New Years Eve countdown), and what many guests don't know is that while a majority of the fireworks are shot off behind the Sorcerer's Hat, there are other fireworks shot off up and down Hollywood Boulevard.
Ideally, you want to stand on Hollywood Boulevard, close to the park entrance. I know it seems counter-intuitive to be far from the stage near the Sorcerer's Hat, but unless you want to be turning your head constantly (and missing something), standing towards the beginning of Hollywood Boulevard will allow you to "see it all".
So while everyone else is moving as close as humanly possible to the Sorcerer's Hat, be sure to head towards the entrance and watch it from there to get the best vantage point to see all the fireworks in all their glory. Have fun!
