Rope drop is hard because if you know you will be really fast and are at the very front or like second row of people, go through the Adventureland rope and past critter country. That’s the shortest distance to the ride.
However, that will only be good if you are in the first like 50 people on the ride at most. And if your whole group is that fast. The line forms off towards the falcon, so If you walk equally fast the critter country way vs the Frontierland way but you are 45 seconds slower than the fastest people, you will have to walk down past the whole line spilling out of the queue towards the falcon and swing around the back of it while the Frontierland rope drop people are joining the line.
Probably a 15 minutes of waiting in line mistake at best, as much as 45 extra minutes of waiting if you have a slow person in your group and the line gets dragged all the way back towards the falcon.
So TL;DR: Are you gunning to be in the first few people? Go through Adventureland. Are you even a tiny bit back at rope drop? Go through Frontierland and follow the herd.
PS - anywhere on the rope is fine. It doesn’t really make a difference because of how long this walk is compared to RSR. And it’s a true free for all there’s no herding by CMs.
