^These photos are from the Fastpass/Single Rider Line and Merge Point. I had the opportunity to experience the attraction tonight for this line and let me tell you, the difference between the Stand-By and the Fastpass/Single Rider when it comes to the design process is very big! In all honesty, I don't think I will be getting a Fastpass for this attraction ever. It is very clear that you are almost punished for choosing to use Fastpass or Single Rider line as your entire experience is now expedited.
For Stand-by, your design mode starts with you drawing a line to form the shape of your car, optimizing that shape, custom selecting specific aspects of the cars shape like the front end, then you move to to selecting color, front wheels, back wheels, front wheel size, back wheel size, and extra additions for the front, side, back, and roof of your car such as spoilers, turbo engines, jet propulsion, Tron lighting, etc. All the choices affect the four categories: Power, Efficiency, Capability, and Responsiveness.
For Fastpass, you select which of the four categories above is most important to you, then you you have about 8 premade cars to choose from, and that is it. Seriously. I knew it was abbreviated, but I was very disappointed. Not only that, but as you can see the design area (which, IMO, looks less impressive than the standby design studio with it's plain white walls) [SEE PHOTO 1 ABOVE], then leads into the rest of the queue to the merge point where it passes glass that looks in on the standby design studio. [SEE PHOTO 2 ABOVE]. Photo 3 above is post merge queue with more glass looking in to the area between the standby design studio and the merge point. (That ramp up in Photo 3 leads to the Exit Sign on the left in Photo 2.)
I'm still very pleased with EVERYTHING, but I'm just nitpicking at this point. I really will advise people NOT to get a Fastpass for this attraction and simply choose the Stand-by queue unless you really pressed for time and only care about the ride (which will be a certain guest demographic).
