I hope you are correct, but I can tell you from personal experience that I am doubtful. See that picture by my name? The day that was taken, we were in line for the safari. At the point where you are required to park your stroller, I take it out of line and park it, and the 2 minutes later when I came back to line, the ladies behind us tried to physically block me from rejoining my wife, daughter and brother. They had been behind me for 30 minutes and had watched me take the stroller out, yet tried to block my reentry.
I really hope there is a good plan for the return-to-line program. In theory, I think it is an excellent idea. But my faith in the average Disney line denizen to play nice and make this work is not high.
I saw something similar, and equally disturbing.
On a very busy mid-day in 2023, the area near the entrance of BTMRR queue was crowded.
Family arrives: Two eager approx 10-year old boys running ahead, mom+ dad come next, trying to keep up. Fifteen feet behind mom and dad comes slower-walking grandma, except the family doesn't notice she's fallen a bit behind. {Actually, since then I've since noticed this pattern happening a LOT at WDW.}
So several families cut in-between mom+dad and very petite grandma. Not line cutting, just funneled. A short- and I mean short distance later- just past the ride entrance- petite grandma has to pass about 10 people to catch up to mom/dad/kids. Mind, all within 3minutes of entering the queue, grandma politely taps folks on the shoulder, "May I please pass you to rejoin my family?" while pointing to her family.
A burly guy loudly YELLS, "No! NOBODY will pass ME!" then continues to verbally berate her for several minutes, clearly standing over her like a giant bull. He's so loud and obnoxious, that everybody in the queue is now staring at him.
Luckily, at that point, mom+dad noticed that grandma had fallen behind. Luckily, the bull's wife also intervened and prevailed upon him to reconsider. He let grandma pass, but continued to bellow for some time.
His instant rage was rather disturbing.
