that's easy jones. Arillas rent-a-car
www.arillas-cars.com is run by Kostas - Anna (studios) other half, and is situated right in the middle of Arillas. You can book before you go or when you're there.
You're right about the locals. We have made many friends in the time we've been going, as have all the forum members. We stay in touch with some all year round. If you want Benidorm forget it. If you want a beautiful beach, laid back atmosphere, very few shops but lots of tavernas and places to eat, some lively evenings (optional)and lovely locals to welcome then you Arillas is IT.
After one visit you'll be addicted, like we all are....
