I'll probably take 16 names to get the ball rolling, seeing as we have several tentatives. Then I'll ask for date conflicts, and see if we can find common date options that work. If there are multiple date options without stated conflicts, I'll have people vote. Then people can research flights (NOT BOOK, just research), just to make sure it is financially do-able, before I ask people to commit. I'd say for 2013, we have a two-month window (mid-Sept to mid-Nov). It is probably best to avoid the holiday season. If we can't make that timeframe work, then I'll start looking at early 2014.
