The Spaceport in Tommorowland is accessable in a sort of courtyard at the edge of Nova Cite. The Space Mountain structure is outside the berm and it not only houses the Space Mountain coaster but much of the rest of the land. When you enter through the doors, you will come into the main hallway. As you proceed down, towards the left is Star Tours which has six different destinations including Tatooine, Mustafar, Endor, Hoth, Naboo and Coruscant. The queue itself has a lot more of an airport docking feel though we do briefly go through the maintenance bay to see C-3PO and R2-D2. In the queue itself you see a variety of aliens waiting to board as well at other docking bays, essentially replacing much of the droid mechanics, though we still have the obnoxious G2 Droid as you get to the load. The safety video is way redone, though now with a Twilek flight attendant addressing you and of course, newer alien species boarding in(somewhere I want to have a sight gag with a Dug having trouble with his seat) Mustafar takes you along the lava rivers and ghostly duelists fight amongst the rocks and even on your vehicle, Hoth features encounters with AT-ATs and the Wampa as you make your way to Echo Base, Tatooine has a close encounter with the Sarlacc and Kraytt Dragon as well as Tusken Raiders and some highly illegal Podracing(as it was outlawed at some point in between ROTS and ANH), Naboo takes you through the planet core and encounters the sea monsters within, and Coruscant has a high speed chase through the city streets as well as an close encounter with one of Palpatine's many clones(as seen in many of the novels, he practically became the Kenny of the Star Wars universe).
Go to the right and you find Stitch's Galactic Rampage which is a dark ride similar to Cartoon Spin. Your spacecraft itself is hijacked by Stitch early on, thus a story reason for the controlled spinning as you try and regain control. From there you encounter Stitch several times wreaking havoc throughout Planet Turo(his first rampage), backing up sewers, reversing street signs and trying to steal every rider's left shoe(achieved by in car effects similar to the mouse swarm in HISTA).
Going straight ahead from the entrance, you will get to Rockettower Plaza. Flying Saucers are on a lower level(accessible by the same ramp Astro Orbiter uses), though the ground floor has a viewing deck. A wide walkway over the Flying Saucers leads to the escalating ramp up to the Tommorowland Transit Authority which goes out from the Spaceport Building and throughout Tommorowland going over many of the areas and into Buzz, Stitch, Horizons and InnerSpace. The ride culminates in the preview of Space Mountain and back to the station. Astro-Orbitor is accessable by a twisting ramp and uses the WDW design.
Finally in the Spaceport, there is Space Mountain. The entryway to the Space Mountain docking bay lies behind Rockettower Plaza with a queue similar to the Disneyland refurbishment and the track itself a new design with an intensity more like Expedition Everest(family friendly, so no loops, but fast) This part of the Spaceport truly is the mountain itself but below the coaster are the show buildings to Stitch and Star Tours.
Next, I will conclude Tommorowland with Mysterious Island and Port Discovery.
