You'll probably see the Tower of Terror and the Earrfel Tower, a water tank with mouse ears, even before you enter this park (formerly the Disney-MGM Studios), which Disney bills as "the Hollywood that never was and always will be." Once inside, you'll find pulse-quickening rides such as Rock 'n' Roller Coaster, movie- and TV-themed shows such as Voyage of the Little Mermaid and the American Idol Experience, and a spectacular laser-light show called Fantasmic! The main streets include Hollywood and Sunset boulevards, where Art Deco movie sets remember the golden age of Hollywood. The Streets of America sets include New York, lined with miniature renditions of Gotham's landmarks (the Empire State, Flatiron, and Chrysler buildings); as well as San Francisco, Chicago, and others. Pixar Place (formerly part of Mickey Ave.) is home to Toy Story Mania. You'll find some of the best street performers in the Disney parks here.
Arrive at the park early. Unlike Epcot, the Studios' 154 acres of attractions can pretty much be seen in a day. The parking lot reaches to the gate, with trams serving the outlying areas. Pay attention to your parking location; this lot isn't as well marked as the Magic Kingdom's. Again, write your lot and row number on something you'll be able to find at the end of the day.
If you don't get a Hollywood Studios Guide Map and entertainment schedule as you enter the park, you can pick one up at Guest Relations or most shops. First things first -- check showtimes, and then sketch out a plan for your day, because many of the of the park's best offerings are its shows. Schedule your rides around the shows that interest you most and go from there.
There's a tip board listing the day's shows, ride closings, and other information at the corner of Hollywood and Sunset boulevards.
