Have never hired a car on holiday before, but having to this year as flying to an airport a little way from our campsite in the South of France. Was about to book the car through Ryan Air at the same time as booking flights, but would appreciate some advice before I do so. The rental agent, Firefly, says in the small print something about having to pay a collision waiver something or other, at the time we collect the car. Looking at their table, this appears to be 900 euros! Is this normal practice? Do we have to do it? Was hoping our own car insurance, travel insurance and credit card protection would be enough - especially as insurance is included in the car rental. Is this normal procedure, that you hand over credit card details for this amount when you collect the car? We're flying to Carcassonne.
