My ex-Dh is taking DSs, 8 and 6, on holiday to France for a week. I am a very nervous flier so didn't want them to fly so he will drive them to Dover then get the ferry to Calais before driving to Paris where he will stay overnight with his cousin and his wife. They will then all get the train to Nice (of all places) before hiring a car and driving to a villa on the outskirts (not in Nice itself). I am terrified of terrorist attacks either on the journey (on the ferry, at train stations etc) or whilst there. It is safe to let them go as I am honestly in two minds. This is only their second holiday away from me so they aren't thrilled about going.
