I've been to the last eight and did the organising for friends/family for the last 7 of those. Every tournament has produced different surprises and challenges. I think accommodation is the big challenge this time although I am resisting buying hospitality at this point. Having all the games so close this time will make internal travel very easy. It is relatively cheap and easy to get to Doha. That leaves tickets and accommodation. The more difficult it is to get accommodation the easier it will be to get tickets.
