I found the last question a bit confusing, as it talks about "how much more...", but it isnt clear what 'more' is relative to. More than the 'actual cost to the organisation'? Or, if the survey participant self-funded their Wikimania, how much more should they spend to attend Wikimania? So I put '0'.
Thanks for going through the questions. You are right, that question is ambiguous; but it's intentionally so, to avoid forcing a single interpretation of where the "more" starts. (I have my opinions, but there is no rule; and past Wikimanias were very different.)
We'll see how well it works; this is just the beginning of a conversation. :)
