It's kindergarten for goodness sakes! It's not like an absence of 2 weeks in kindergarten is going to prevent your child from getting accepted to college.

All this talk of "curriculum" that will be missed is just silly.

Go and have fun!!
Well, I suppose that too depends on your district.
My son went into kindergarten without being able to read. He had a basic understanding of phonics (and with that was advanced for his class), and could count dependably to about 30. By the end of kindergarten he was reading (and reads pretty good), could count to 100 and do simple addition. Could count by 2s 5s and 10s to 100. Could spell simple words and label his drawings and write simple notes. He did this by going to kindergarten 2 1/2 hours a day for 38 weeks. Missing two weeks is missing 5% of the school year.
My daughter just started kindergarten this year. She already does most of that, so she wouldn't be "left behind" on the academics missing a few weeks. But she needs every minute of the social experience - she needs to catch up on appropriate school behavior (which includes showing up and participating).
I doubt two weeks will keep them from getting into college. But two weeks in kindergarten would have made the difference for my son between being in the high reading group in first grade and being in the middle group. And you can't plan for illness and accidents - its possible that two weeks will get added to over the course of the year to the point where your kid does feel the pain from those two weeks. In fifth grade I went to school for a grand total of 75 days - we moved twice, we had a teachers strike, they closed the school for a few weeks in winter for the energy crisis (they were going to make it up in the Spring, but we moved again), I had tonselitis. I even had two Spring Breaks due to switching schools! They almost held me back because of it and the only reason they didn't is that I'd been in a advanced program at my first school that the new school didn't have.
Perhaps your kindergarten is less rigorous or your kids are brighter and better adjusted than mine. But around here, kindergarten is not learning blue and playing in homeliving - kids are expected to have that before they start.
I'm not against pulling kids from school - ours will miss three days in October. But I tend to agree with Mrs. Pete that vacations can be taken in a manner that impacts the school year more minimally. Two weeks is a long time in a kids development (think back to being a kid and waiting two whole weeks for your birthday and how much "stuff" happened and how long it took - time is different when you are a kid).
As a former manager, I wonder if this is what some of my employees with attitude problems were taught - they wondered why they didn't get good reviews, but wouldn't change vacation plans to be minimally impacting to the business. They were the first to get laid off, too. But "its MY vacation, I get to take it when I want" was what I heard when I tried to say "that's a bad time for us."
