How about this answer...I can't.
While most of the US states still have more liberal attendance laws, a handful have strict laws that make it illegal for parents to take their kids out for vacations (or really anything unexcused). In our state, more than 2 days of unexcused absences in a 60-day period is considered a violation of the law. If your school admins choose to pursue this, you could wind up in court facing fines and misdemeanor charges. There are a couple of states that actually have jail time written in as possible punishments for parents on their first offense. And to just show you how strict they are, school trips to educational places like DC now have to happen over holiday weeks as they violate attendance laws. My friend even spent over a week proving to a court constable that her son was legitimately out for a death in the family.
The reality though is that more states may be seeing this in their state attendance laws. One of the morning shows was talking about this the other week and I guess more states are considering enacting such laws. While I'd like to think it's for the kids, it's done for funding. More kids in attendance = more funding for each respective school/district.
And I know every time I bring this up, I get people saying they'd never follow this and the govt has no right. Technically, if you've signed your kid up for public school, you've agreed to the laws governing their enrollment in said school/district. I know people like to talk a good game, but do you move to a new state? Do you home school? Or do you leave them in public school and deal with all of the legal charges and fines as they roll in each year, hoping that a judge won't escalate things and take it beyond the basic penalties? Because you're never going to win in court if you try and argue you have a legal right to take your kid on vacay vs. sending them to school.
I'm mixed on the matter as I see both sides. On one side...I want the freedom to vacation when prices and crowds are low + while I don't feel WDW is nearly as educational as other trips, kids do learn lots from vacays. On the other side...my parents pulled me out for trips and I missed some crucial lessons that I really shouldn't have missed. No make up work could compensate for what I lost by being out of the classroom.
Just food for thought
