Argument here possibly runs deeper than if you should or should not do it.
How long prior to the time away being taken was the request for term time leave made? Did the school reply in time, before a booking was made? Life goes on and I'm aware that simple admin tasks often take excessive amounts of time. The case has been heard in court and the court ruled in favour of the school (? I understand) - so was it fair, or has an example been made of these people?
Maybe given the economic climate, and threat of things gettng worse the local authority fear that excessive numbers of parents will take children out during term time.
This is something that should be judged on a case by case basis. If the child can cope with a few weeks out of school - i.e. will not fall behind, will not require additonal support on their return and there is a commitment from the parent to do any extra work necessary then leave can, and should be granted.
Travel broadens the mind. The ability to take a holiday allows a family to spend time together and interact in ways that are not always possible at home or with the distractions of day to day life. If this can be taken without a paying a premium price and/or not getting a fine at the end, it leaves more money in the family budget - from which the children benefit.
