Obviously, they can't make you take it and I doubt whether they'd charge you for it.

Last year, in July, we had a package booked with Direct Holidays (Thomas Cook now). A compact car was included in the package but it was cheaper for us to book a full size, including insurances, direct with Budget than to pay all the insurances on the so called 'free' car. I didn't bother telling Direct Holidays that we wouldn't be taking them up on the car. Never had any comeback. HTH.

Have you compared the cost of booking your flights and accommodation separately, rather than booking a package. It could be cheaper and you could decide for yourselves how you want to get around - either by hiring a car or transfers. There are some good deals on flights and loads of different types of accommodation around.
Good luck.
