Off on a Ryanair 1p day trip on 2 Dec to Gerona, Spain. Searched using Moneysupermarket.com (after many other searches at expedia etc) and I couldn't get over this bargain:- Pick up and drop off at the airport. If you want cdw you add on £2.50. I recommend it having coughed up £600 excess whilst on a cheapy holiday in Spain once. So with basic CDW you will pay £7.50, still a bargain IMO.
You can't even get the bus for this price!
Please note that if you use moneysupermarket, you will see other cars come up for Sixt and Expedia but when you click on them the deals don't exist....naughty
