Delphiniums I'm not sure that there is anything else in that situation, and that it's probably too late for much else. I agree that I would try force if possible, that the problem of the timeframe is what makes it difficult, and that abandoning the holiday (even just me and the DD) would be only my absolutely very last resort. I also agree with you, 5tratters and others that the parent needs to stay the parent, and the child needs boundaries.
However, with respect I disagree that there is no evidence of AS, and that just because the OP doesn't mention it, it definitely isn't a possibility/consideration. Most girls with AS are diagnosed much later (that kind of age is common), often only after behaviour comes to a head, or secondary mental issues come up. A lot of PP with experience of AS refusers have been saying that this does resonate with them, and that physical force isn't always possible, and even with a lot of preparation and strategies, a situation like this could still happen and not be immediately resolvable.
That said, OP has not given us enough info - it equally could be NT child out of hand, Queen Bee, etc or having a hormonal moment, and I think all the talk about how an AS child is handled in this kind of situation is going off topic a little; I parent my AS DC differently to my NT DC. Though as Fav says, even if she's not AS, we all have spectrum traits and handling this type of situation accordingly can help.
I like the horse analogy either way. Looking for the underlying reason, sorting that out, remaining outwardly calm, defusing it, and not escalating it to a battle of wills. I haven't yet parented a teen, so very interested to read other posters suggestions and advice here.
