I’ve been eyeing the 2025 academic calendars for 4 different school districts in 3 different states trying to plan an extended family vacation to WDW and I’m surprised at the differences between them. One has a week off in early October, one has a week off in February, two have a week off in March, the other two have a week off in April. They all have some time off in late Dec., three also have the first week of Jan. off but one does not. Two finish school in late May & two finish in mid June.
Since your child is in preschool ATM, you have several years before you need to make these decisions. Once your child starts school their school district may have one of those odd weeks off, like an October week or a February week, that you can work with.
If not, once your child starts school you can have a frank conversation with their teachers about the impact the absence would have on your child. Different states & school districts treat absences for vacation differently. When my now adult son was in elementary school pulling him out for a week could be an excused absence if I had worked it out w/ his teacher (note, I rarely did this because although he was academically gifted & had no trouble keeping up, I quickly learned that I didn’t enjoy being a ’teacher’ on my vacation

) these days that’s not the case in my state & pulling kids out for vacation is an unexcused absence.
So there’s really no one size fits all, it depends on your state, your school district, & your child (w/ input from said child’s teacher.)
