I always disliked events that had turnstiles in the entrance since that is how they count visitors.
Unique count should always be guess purchasing one ticket for either a day or weekend, and they get counted once.
Guests at some of the events out there get counted up to 8 times a day becasue they go back and forth.
The proliferation of for money companies like Artexis and easyfairs has been awry. We have the same issues up North with Comic Cons brand "heroes" which is the same as easy fairs franchise for spain, doing the same thing. They purchase the rights, to have the name, and then they organize a half assed event with little or no focus on artists, comics, or the things that make comic con great. Its soul less and I feel worse and worse about the people that run it.
Counting guests is also a shitty shitty way to seem "big". You might have 60 k guests but how many of them are happy. How many were engaged in events. How were the events and how much room was there for them to experience things. Things that are always left out. God I hate commercial enteties.
Still, Japan Weekend is probably (since i havent visited them all) the best event out there according to what I've heard and experienced. I like the people there, and the content is good. There is room to grow, and focus has to be spent on adding content. But they are in the right track!
