I will be buying a ticket for the weekend only.
I see that they offer few different areas on the venue for differnt price.

Weekend ticket for area B is 60eur while for area D 35eur, quite a difference.
I was wondering, from your past experience, how important is it to get a good seat ? does it worth the extra money (almost twice).

Looking at the pictures in this thread, It doesn't look like it is that big, so the different seating areas should not make that much difference to your view.

Don't blame me if it does though!:D
