Try http://www.kayak.co.uk for flights. You can sign up for daily email alerts so that you can monitor prices.

You could also try Expedia for a flight + hotel or try some of the bed banks such as Travel Republic, Alpharooms, etc for hotels.

Be aware that fly drive may include the car, but won't include the insurance which is very expensive if you take it out once you land. Better to book your own car hire with Carhire3000 or Netflights.
