Don't count on early booking working. I ordered 2009 tickets at the first possible moment last year, asking for 3 alternative campsites. I got Beausejour - which wasn't on my list. I asked them why they couldn't fulfil my order, given that I've been buying tickets from them directly for 10 years and put my request in at the first possible moment. Their response: Lots of people ordered before you and the sites were full up.
