I've found that it is now much easier to get a parking spot straight away, along with getting in and out of the place.  

I did read that some shops will validate tickets so you can park for free.  Even at 2 - 8R that is still so much cheaper to park then where I come from in London.

I am told that before people were parking at CC for free and getting a cheap cab to the airport.  (dont know if thats true but there is an improvement)
