We are due to travel to France by car this Friday (19th Aug) for 2 weeks and 5 year old ds passport expired in April this year. Do they check every car and all passports at the chunnel???!!!!! Can we just hope for the best that they won't notice - there are 4 kids!!! However I travel on New Zealand passport - so they might check us out? Please any help or experience of this would be welcomed! Thx
