Hello everybody I would like to visit the star trek convention in frankfurt and have some questions. Hope you can help Which of the"highlights" are recommendable? foto shoots? talks? night party ticket? Is a standart ticket recommendable or do i really have to pay for every additional stuff? Whats included? Can i also bye some of the additional tickets at the convention or do i have to preorder this tickets? I think the homepage is not really helpful ... thank you in advance
