It's £5 to get in after 5PM but free before hand although you have to be searched. Team Germany had a shop and they were selling things 2 for 1 so my badge was £5 for two! You could also have your picture taken in a beach chair from Mecklenberg/Vorpommern which I think means Pommerania. And besides the food and beer in a German Bier Keller that was it.
Would I go Back? I think I've done all it has to offer.
