My wife says (who’s a teacher )get a holiday form and be honest and that you can not be fined unless the kids are off for 5 consecutive days or more. I should mention we will be taking our 11yr old and her friend this year to keep her company and our school has been fine ,we did take her out last time (2019)and they were fine with that too. Have fun, it’s a different festival with kids but still great. You’ll see stuff you might not normally see.
Have a great festival it’s going to be magic again 🥳
