I would like to look at this issue from a different angle.
Like most people of our age, we never go away in the school holidays, preferring to avoid other people's children now that ours have grown up ! We therefore go away, in this country and abroad, in May (avoiding half term week!), June, September or October.
Just imagine if parents weren't prevented from taking their children away in term time? We honestly wouldn't know when would be a quiet time.
After all schools are closed for 13 weeks a year which is ample time for holidays and breaks, as we did when ours were young.
Yes I know it is cheaper in term time, but having children is all about having to make decisions according to finances isn't it, and holidays are one of those decisions.
There have always been cheap holidays like caravanning and camping, so there really is no excuse.
Those of us who are older, as well as those without children also need and deserve a break, but away from others' little darlings!!
