If you look at the distribution of current bitcoin nodes, a huge proportion are already in the US.
So I vote for anywhere outside the US as a conference location.
That makes no sense. I think one more, large event, sponsored by a few sponsors getting together rather than one head behind it all, in the US. Bitcoin users should think logically and realistically about it's users who are most likely already financially invested in BTC itself, and determine the meeting place based on a location that offers cheap air fares and hotel rates. Better organization, rooms in bulk deals, I know there has to be a few people with con and expo experience to get behind the next event.
This is why I like San Antonio. I have five years of experience working with these types of events and have lived here my entire life, so I have a lot of contacts. Our convention center has more than 1.3 million square feet of usable space and is within walking distance of dozens of hotels, the newest of which is right next door with 1000 sleeping rooms. The convention center also has:
67 meeting rooms
4 exhibit halls with over 440,000 square feet of contiguous exhibit space
3 elegant ballrooms including Ballroom C with approximately 40,000 sq. ft.
Full service UPS Business Center
36 loading docks, including 24 covered docks
Not to mention the Alamo, the Riverwalk, all the great shopping, the restaurants, and the many theme and amusement parks, including the world's largest SeaWorld.
Hmmm, looks like March 4, 5, and 6, of 2012 might be a good time, right after
FIRST has their robotics competition (March 1st, 2nd, and 3rd). The weather will be great at that time, too. Let me see what kind of room rates are available.
In any case, how does March 2012 sound to everyone?
