Would have loved to be there, but it is just too complicated and also quite expensive to get there from here, even travelling with "budget airline"! Carcassonne looks beautiful!
The key point is whether you have cheap direct flight to Toulouse. From there take the train. Done.
If not Toulouse, Montpellier is another option.
Carcassonne is possibly the nicest venue of the tour. I would like to go too but it's pretty far and PC/MK have sent me up in Germany two days before.
And the presale is coming so quick... What saves me is I don't trust the presales anymore. Will probably wait for the regular sale to decide.
