Defcon has CCC beat in this area because you know you will get a ticket at Defcon. On the flipside, Defcon 27 last year was a complete mess because there were so many people. It was more Linecon than Defcon. However I am thankful to DarkTangent and his crew's efforts. The Goons did the very best they could and I am glad they are still doing it.
At 35c3 I got totally ripped off by Leipzig Taxis and my hotel which was cheaper but further away and not on the train path(at least easily).
Was it worth it? YES. Was worth every last penny. I am so thankful to the Chaos Computer Club for their efforts in putting on such an amazing event year after year. If I manage to make it back there again I will be volunteering as an Angel. I just wish it was cheaper to make it to Leipzig from the US but I understand that they are stretched to the gills in terms of capacity.
I heard a rumor that they have already maxed out capacity at Leipzig and there is no bigger place in all of Germany?
