What if that is the FP line and the standby line is even more detailed?
Also I have to assume FP is turned off just like at MF:SR for the foreseeable future.
Rise of the Resistance ride spoiler
You enter through the Resistance turret outside, through either the single rider, fastpass or standby lines.
Standby takes you through the tunnels and is a great queue. You end up in front of 2 doors. BB8 is there and he projects a image of Rey where she asks for your help.
Fastpass skips most of the tunnel queue line and gets you to the BB8/Rey Message.
Single Rider skips all of that and get you to the ITS shuttle.
All 3 lines ends up heading to the ITS tle in groups of about 45-50 people/ You board the shuttle and Nien Numb is your pilot. You see Poe take off in his Black/Orange XWing but the First Order show uop and Poe goes for hekp as your shuttle is captured by a Star Destroyer.
You exit the Star Destroyer in a giant hangar bay - you see 50+ FO troopers as you are escorted to detention cells. You are broken down into smaller groups and board the 8 passenger transport vehicles.
A droid helps "release" your vehicle and you are paired with a second vehicle and you have an adventure driving through the halls of the Star Destroyer.
You come upon a pair of full sized AT-AT walkers and you vehicles each take an elevator to the second floor while being shot at by FO troops.
You continue the adventure, twisting and turning and running into Kylo Ren a few times. You drive between 2 giant guns as they are firing on the Resistance in space.
Finally your cars head to escape pods and you fly back down to Batuu only to crash into a giant ship before you get out and exit back to the Resistance camp.
