August 27th-30th - Discworld 2010 in Birmingham
September 2nd - 6th - AussieCon in Melbourne
We'll probably skip the first, since (a) it's gaming only, and (b) we're not totally insane.
(Having just completed 3 weekends in a row of Fasnacht, then PicoCon, then PCon, but at least that was all within Europe.)
ETA: rmc28 has just pointed out that Consternation is in fact next year, not this. Phew!
