Rather like a toddler who repeatedly pushes beads up its nose and wonders why they get stuck, we keep going on holiday with two small children and wondering why it’s not the relaxed experience of yesteryear. You may well recall that my lucky-mushroominess doesn’t extend to airports. This time it was a mere six hours at Heathrow’s Terminal 5 (fog). Compared with our eleven hours at Alicante back in January, this was child’s play, although the crummy situation was greatly exacerbated by the fact that there was no… child’s play. Which brings me to my point: where are the playgrounds in airports?
