Getting out of there was logistically easy too. You can book a bus directly from the festival straight to the airport on the Sunday. €25
We got the wrong train on the Tuesday and ended up 30 minutes in the wrong direction before a ticket inspector informed us. Drink had been taken
Ended up having to get a taxi cause it was too late and that was €45 each between 4 of us. Not bad really considering it's a 2 hour drive!!
