That's actually a good question.
Is it actually hosted in Abu Dhabi?
It's run by a Prince of the United Arab Emirates who's a huge fan of jiu-jitsu and grappling. For those who don't know who H.E. Sheik Tahnoun Bin Zayed Al Nahyan is, that's really the simplest way to explain it.
I honestly have no idea. When I went in 2005 and 2007, I went as a guest of competitors, and so I was on the mat. Since I can't go to Barcelona, I haven't looked.
What are the prices like?
It's listed on the ADCC Barcelona website, though.
Yes, there are. There are a ton of grappling fans that flock to the event to watch. It's an invitational, so it's not like at the Pan Ams or Mundials where the stands are packed with competitors. It's a lot of fans.
Are there even tickets for regular fans just to watch?
