Located in Tomorrowland, Meet the Robinsons: Keep Moving Forward is an exciting dark ride through time. Guests enter a queue themed to Lewis' new house, where pictures and home videos retell the story of the film and show how Lewis is adjusting to life with his adoptive parents. At the end of the queue is the garage, where an animatronic Lewis greets visitors. He tells them that he's just finished building the world's first time machines, and invites them to come on board after telling them how to be safe on the ride. These time machines are rocket shaped and are separated into two rows, each of which seats two people. At the front of each time machine is a screen which Lewis uses to communicate with the riders.
After guests board their time machine (each of which is named after a different character from the film), they take off. The time machines are lifted into the air via a rail (think Peter Pan's Flight) and zoom down a swirling blue tunnel, building up enough energy to go back in time. They find themselves in the age of dinosaurs, where digital effects and animatronics bring pterodactyls, velociraptors, and triceratops to life. This peaceful trip into the past is interrupted by a massive T-Rex, who roars at guests, blasting hot air in their faces.
Lewis tries to calm the T-Rex down, but to no avail. It swings at the time machines, causing them to rock from side to side, and opens its mouth to consume them. The time machines take off once again, narrowly avoiding the dinosaur, and head forward in time. Guests find themselves watching the construction of the Egyptian pyramids, and head around and inside them. The time machines nearly collide with one of the pyramids, but are able to pull up just in time to avoid certain death.
They head forward in time again, with a nervous Lewis saying he thinks it's time they head back. Unfortunately, the time machines don't quite make it to the present day, and instead end up in the middle of a naval battle between two pirate ships. They avoid cannonfire for a while, but are eventually hit, and start plummeting towards the water. The time machines are able to muster up just enough energy to travel through time once more, but because of the damage they've taken, end up in an alternate timeline.
In this world, Doris was never defeated, and humanity is still enslaved. The time machines fly through this dystopia, dodging attacks from Doris' many clones. They eventually reach this timeline's version of Lewis' garage, where he's able to repair the time machines. Suddenly, the garage is ripped apart by a massive Doris clone, who attempts to smash the time machines. They take off just in time, tearing through the massive robot and returning to main timeline, although they end up in the future rather than the present day.
The time machines take a scenic journey through this utopian future, traveling through towering skyscrapers and flying past the exciting attractions of Todayland, before finally returning to the present. Lewis thanks the guests for their help and admits that the time machines still have a few kinks he needs to work out, but vows to keep moving forward, before visitors exit the time machines.
