ok Doug, maybe you dont have any kids. Just wait till they tell you 2 days before they have booked a flight that their passport expires 5 months and 3 weeks after the departure date.
i tell you, it is traumatic, and luckily we live only 1 hour by train to Bris city. Last Thursday we travelled twice up the rail to the city - 1 hour each way that equals 8 hours for the two of us. If any of you guys are in the bush, NSW, far away, forget your travel plans.
