Be aware that when you rent a car at Alicante airport, they no longer automatically provide you with a warning triangle and hi-vi jacket - although you are required by law to carry these in the boot of your car.

You now need to request them at the rental office (not the desk in the arrivals hall), where you would normally go to return the keys at the end of your rental. They will then charge 30 euros to your credit card, which is refunded to your card when you hand the items back .

There are big multinationals like Hertz , Avis, Budget  etc
