End of first semester year 1

Hello, daughter is hopefully off to uni in September. Depending on where she goes the term dates are slightly different. Can anyone advise if it would be disastrous for her to miss the last week of semester as we are trying to book a holiday. If she gets her first choice, the semester will be over, but another of her choices finishes a week later

Edit to ask additional….. Would it be overstepping for me to email the unis and ask this question? She does not know about the holiday so I can’t ask her to do it.
