Anybody taking their kids out of school for free dining at DW? I know this has caused great debate in the past

I mentioned to my SIL that we plan to take our kids out for trips down the line and she freaked. She works for a school system and yelled at us for being 'bad parents'. I politely told her that it was our decision- then she brought up fines- and I once again told her, I'd be glad to pay
She went on and on about 'how much time kids get off' and how parents can plan trips during the summer. I told her I wasn't going to pay 4K for a trip in July, when I can book the same trip for almost 1/2 that AND have less crowds. In September airfare is over 100 bucks cheaper to Orlando than in July. Multiply that times 4 people and that's 400 right there.
IMHO-if your kids get A's and B's in school, and have no behavioral issues, taking a grade schooler out for 5 days isn't going to ruin their lives. If we have to pay a fine to the school for removing them- that's OK by me. I'd much rather go during free dining, when the crowds are much less, than fight it in July with every other 'good parent'.
