Sorry, it's undiplomatic to interfere with others budget plans - but I just can't ignore how the future of Wikimania will look like if others will follow UK plans to invest £40,000 only for the bid process (about 62,000$).
I wrote my last response on that few minutes ago:
"Hire a production company for half of this cost. It's really waste of donors money, for what we expect to be done by volunteers, or for a minimum costs. If every one who going to bid for Wikimania will spent this amount of money (and why them not? if UK can, why others not?), it's mean that for 4 places every year we are "spending" more than 260,000$ only for the bid!!!. --188.8.131.52 19:22, 25 August 2012 (UTC)"
I really think the "Wikimania" groups need to speak about that. It's the first time a group/chapter spending such amount of money for bid, and it's open a door for next cities to do the same - with money which can uses to invest in Wikimania itself.
