Zebra! (A bit shocked when I saw my name there in caps and bolded!) Must have missed those threads.
Everyone else who says it's wrong to take them out in term time - yes, I agree! But my DS1 is in reception and this will be the first year we have to take holidays in school holiday time. When I looked around for something we could afford I was amazed at the hike in prices (yes OK maybe I am naive). I'm not talking about 2 weeks in Mauritius (I should be so lucky!) Just a week in Cornwall or Wales. Like someone else said we can't afford much more than £200 and we can't find anything. We are buying a tent for next year. However this year my parents have booked at cottage in Cornwall for the week before half term in Oct and we are going with them - all the sch hol weeks were booked already. Do you have to be in some secret club to get those weeks?
Another point - when children are young (primary) don't you feel holidays can be as educational as school? Last year in Cornwall my DS1 learned loads about nature, how and why tides happen, and loads of interesting stuff that would have been less well explained in a classroom setting.
A friend of mine who has a dd in yr 1 asks the teacher for a list of the things the kids will be covering the week she is away and does homework with her a couple of nights while they're on holiday. I think this shows initiative and thoughfulness, not the recklessness that some posters seem to believe!
Fortunately for us, DS's school seems to agree that education doesn't only happen in the classroom and that parents taking their children on holiday is a positive thing in most cases.
Anyway - what about lobbying the travel co's and holiday camps to stop their blatant profiteering from school age kids?
