Does anyone have any experience/knowledge of either picking up guests from the airport, say in a minibus (normal license) whether I would need to get a special insurance. I had also planned to take guests to certain spots using my van which has some seats which you just put in. Does this type of activity contravene any french law, especially where insurances are involved. I know people do this for vineyard trips etc or painting locations but how do you do it? Is it legal just to have normal insurance for the vehicle - the passengers wouldnt be paying a fare or anything like that, it would be part of their holiday package. Many thanks janeyd
