The cliché that comes to mind for me at Disney-MGM studios is "quality over quantity." This park is small, but it has some of my favorite attractions in Disney World.
I'm a huge fan of "Star Wars," the Muppets, and "The Twilight Zone," and this park has attractions connected to all. Star Tours is a galactic sightseeing tour that goes awry. For me, waiting on line is almost as fun as the ride itself. Between R2 and 3PO and the videos of other destinations, waiting to board the ride is a charming time (although I had more fun in Euro Disney, where 3PO talks French and English . . . Protcol droid indeed!). Also the instructions are fun, with wookies and ewoks boarding the shuttle.
Muppets 3-D also has a fun wait, with a video starring Sam, Rizzo and Gonzo. Muppets 3-D is mainly a movie, but also incorporates bits of live-action and animatronics.
The wait for the fairly new Tower of Terror doesn't have the same attraction, but the ride lives up to its name. You board an "elevator" which ends up leaving its shaft and then turning into a freefall ride. The word is that it's never the same ride twice; that each shaft offers its own intro and the drops change constantly. We only rode the ride twice, so I can't tell how true that is.
MGM has its own version of "Who Wants to be a Millionaire," in which all people in the audience have a chance to play and possibly win a Disney cruise.
Like all the Disney parks, MGM offers a multitude of restaurants, each with a theme of its all. My friends and I ate at the Sci-Fi Drive-In (look for separate review).
There is a parade around midday, where the characters of Disney, Henson and Lucas ride around in some pretty spiffy cars. A hostess, much in the style of Joan Rivers at Oscar time, announces those riding down the road.
The Aerosmith Rock and Roller Coaster is somewhat like Space Mountain, in the sense that it's an indoor roller coaster mostly in the dark. What makes it different is that you are riding in a stretch limo and the launch is one of the fastest bits of any ride in all of Disney World.
The night is capped off with Fantasmic. Wizard Mickey fights a number of Disney villains.
MGM and EPCOT are for older patrons than the other two parks. Still there are a number of things even the youngest should like, such as the usual Disney characters and the "Honey, I Shrunk the Kids" Playground, where kids can play with super-large toys, made to mimic the backyard scene from the movie. Also, Disney Playhouse should be good for younger kids.
