No they didn't! They have some stuff to explain!
Also we bought for 50€ coins for drinks already and we couldn't get the money back for that.
Then yet the tickets, the gas for driving there, the camping costs and costs for the taxi... all gone!
The organization will have some explaining to do why the hell they just cancelled the total thing at that moment and not 2 days before when there was already a warning that it would be storming! If they had done that everyone would have lost only money on the tickets and not on all other things.
