holidaying while 38+2 ?

Michelle • 33 year old from Australia , currently pregnant with baby #4 a boy..miss 7 mr 5 miss 1 and prince due 26/01/17
So January every year we go to our holiday house for 7 days , which is 3 hour drive away . I'm due with my 4th jan 26th and we are meant to leave jan 14th . My last 2 babies come 38+2 and 38+1 last one I just made it to hospital it was a 20 min labour . Now my family are all oh how nice to have the baby while we are away but I'm scared I'll have him while driving 😳 what would you all do ?
