we wish we did it more. Once kids get to middle school - it's NOT the school it's the activities / sports that really begin to interfere with family vacations year round.
So YES - we did, needed to do it more!! My we got my kids homework ahead of time from the teacher(s) - they were NOT amused!!! They did the required work and after a one week vacation, they were usually 3 weeks ahead of the class!!
Public Schools (frequently) get "paid / funded" by the number of butts in the seats, and a student on vacation for a week will have an impact on funding - but Who Cares!! Family time is IMPORTANT.
And my kids have learned a lot by exploring the world. We are Lilly white (I'm getting sick of the "beached white whale" comments while I'm enjoying some time at the beach

) and from a predominately white state, therefore walking around the towns in Caribbean was an eye opener for all of us. Then visit the sugar plantations. More education! And then there are the historical cruises in the Med and Northern Europe - lots of education there. Alaska - learn about glaciers and critters!!!
There's more to life than just book learning. Getting out into the real world helps cement the book learning. Need Both.
