You must be really out in the sticks (I'm from south Northumberland originally), were flying back to Newcastle on easyjet and it was only £30 each from CDG but because were on the metro line it only costs us a couple of £ to get home. You can get really cheap airport parking if you book really early though - and I promise you Bob if you can manage the multi storey car parks at the metro centre you will be fine at the airport!
I went with ledger about 5 years ago but we got the coach from Newcastle and it took a looooonnnnngggg time but I will say they were very professional and a good company to go with
