Just to clear things up as to how everything in Tomorrowland fits its theme, as a Tomorrowland Ops Cast Member...
Tomorrowland is a space community where aliens, robots, humans, and other intergalactic beings coexist peacefully. It is governed by The League of Planets and is actually a very bustling little town.
Stitch's Great Escape! - The Tomorrowland Interplanetary Convention certer is currently being used by the Galactic Federation (a police force dedicated to preserving peace and harmony throughout the galaxy by "protecting the nice from the naughty") as a prisoner teleport center. They took over the facilities from a corporation called XS-Tech in 2004 after a nasty incident resulting in the loss of a life tragically transpired in one of the teleportation chambers. The facility is currently used to bring in prisoners ranging from Level one (common misdemeanors) through level four (extreme high security crimes), where they are held until a cell has been assigned to them, at which point they are teleported outside of Tomorrowland into the Galactic Federation Prison Facilities.
Monster's Inc. Laugh Floor - The Tomorrowland Science Center, across the Avenue Of The Planets from the convention center, is currently housing an open house by a visiting company known as Monsters Incorporated. This outside company has found a way to create extremely efficient energy by harnessing human laughter and has come to Tomorrowland to demonstrate this discovery. By working with technology created by XS-tech in the mid-90's, they transport visitors to their factory in the city of Monstropolis by bringing them through a "teleportation door" (the first and only of its kind). Here, humans are treated to a comedy show by some of the factory's top comedians and shown how their laughter can power an entire city.
Tomorrowland Indy Speedway - This is Tomorrowland's super highway, for those residents who choose to drive motorized vehicles. Most vehicles in Tomorrowland are driven purely for novelty purposes, as the main mode of transportation in the city is the Blue Line. Traffic is always clear here.
Tomorrowland Transit Authority - This is the main mode of travel for the city of Tomorrowland, the Metroliner. The Metroliner features three lines- blue, green, and red. Blue is the most popular and is the only line that humans are allowed to use. They generally board it at the main station at Rockettower Plaza. It makes stops all throughout the city, including Perfect Park Acres (the latest in Hoverburb community) and The Interstellar Hair Salon. The red and green lines are reserved for visiting robots and alien citizens, respectively.
Buzz Lightyear's Space Ranger Spin - This is the current headquarters of Star Command, an elite group dedicated to protecting the galaxy. Guests enter as part of a recruiting drive, but soon discover that their help is needed to defeat the Evil Emperor Zurg.
The Carousel of Progress - This is a presentation of an old Earth artifact that was acquired by The Tomorrowland Metro Retro Historical Society and is now being restored and opened for viewing by the curious general public.
The Galaxy Palace Theater - This is Tomorrowland's main entertainment center, and hosts a galaxy of concerts by artists from all over the universe.
Space Mountain - This is another transporation service offered by The Tomorrowland Transit Authority. Citizens needing to travel to far off places may arrange for their personal rocketships to be waiting here for them to board for their trip at the exact moment they are needed.
Astro Orbiter - Also known as The Personal Rocketship Docking Lot. This is where incoming visitors to Tomorrowland are allowed to park their personal rocketships. An intergalactic parking garage, if you will.
There you have it. The all-encompassing theme of Tomorrowland.
