I have 3 kids, they are in 9th, 4th, and 1st grades this year. They will be missing 4 days for our vacation. I told their teachers already (at meet the teacher night) that they will be out and what days and that I will remind them 2 weeks ahead of time. The only one I even slightly feel worried about is my highschooler, but she gets all As and while I know it will be unexcused, it is what it is but I don't agree with it, as she has no choice (though she'd choose to go to Disney of course!) in what her parents descide she is going to do. It is not as though she got on the bus and then ducked around the building to go to the mall or something. I am going to ask (just for 9th grader) that her school record note family vacation next to unexcused.
So far none of the teachers have said anything negative. My younger dauughters' teachers saaid something to the effect of "I'm jealous of families who can go on vacation whenever they want, no problem." We went on to explain that we cannot go on vacation whenever we want. My husband's company is in the restaurant buisness, mainly an ice cream and family dining buisness. Summer and other school holidays are their busiest and therefore he is not able to take time off during that time (other than maybe a day here or there). Thanksgiving is not too busy for them, plus with the holiday and 2 weekends we are able to make a week of vacation (the most he is allowed to take at one time) into a week and a half vacation. So, while some would say we are wrong for taking our family vacation when it involves the kids missing school, I would argue that any other time of year would not be a "family vacation" as it would be missing dad, and therefore we would not be our family. So, you do what you want or need to do for your family, but be honest. No matter if your kid is sick, on vacation, at a family emergency or whatever, it is your child and your choice to keep them home from school.
