DD's ability to queue hinges entirely on the type and layout of the queue, and the way it's managed.
There's no challenge for her in waiting (as there can be for some) as she has no intellectual impairment or processing issue that affects this - give her a seat, (and allow her to sit in it how she wants, which is a different fight sometimes), her music and something to read and she'll be perfectly happy all day long. Too, she can physically stand for longer than most as she's physically fit and healthy.
However, she cannot stand still. She just can't. Something in her nervous system and the way she processes the world just won't let her.
She stims to ease this by dancing. It's gotten 'better' and more subtle as she's gotten older but it remains the case that if she's stood in one place for more than a minute or so, she starts moving - foot to foot, between ballet positions, spinning, tiny hops and jumps, twists and contractions, flicks of her hands and arms.
If you don't know her, it wouldn't 'read' as 'stimming' necessarily, because she's a pretty highly trained dancer these days, and so her movements are coordinated and drilled to be 'graceful' but it is. It's compounded by the fact that she nearly always has headphones in with music playing if there are other people around as she uses that to cut off outside noise she finds painful - again, it won't be visible but she's incredibly sound sensitive. She prefers this and finds it more effective than other options but it also doesn't 'flag' there's a problem.
At 7 or 8, she looked like a fidgety kid and no-one questioned. At 14.5 - they do, because it's way out of age norm for a full sized kid (she's taller than I am) to start jigging about and not be able to stop. There's also far more risk of their not being enough space for her to do it without bumping into people or thing, or just not enough space at all.
So, an outdoor queue, well spaced out, not boxed in or switchback so there are people on all sides - she'll be fine, if getting some odd looks.
A tight queue, indoors, particularly if there's a lot of sensory input like artificial lights, echoey, sudden, loud or high-pitched noises, no room to move, people in all directions, people shouting instructions or talking to her or touching her.... no chance. She's got about 5 minutes tops and then we're in trouble.
