If it speaks to her …not just that she likes meeting people but how she took advantage of the opportunity to learn, expand and grow (with examples)- then I think it’s fine.
It needs to be about her, not the trip.
I think at most schools, the essay is overrated - likely neither helpful or hurtful. So I wouldn’t over think guidance. If this subject truly excites her, then great .
Good luck.
Edit - then again, he says no bueno. But he’s just an opinion.
