Gatinha and I "went" to DragonCon a few years back... not on purpose, purely by accident... and had a BLAST!
The hotel room we were booked to be in "got flooded" (translation, the football team wanted another room), so we got bumped over to this other hotel... and they were sorry, but its the only room they could find in the whole city, and, again, they were sorry, but its also the headquarters hotel for DragonCon, and, again, they were sorry, so they hoped we'd accept the stay for free, and a pass for a free stay in our original hotel whenever we are ready to cash that in. Again, they wanted us to accept their apology.
Yeah we accepted their apology... BECAUSE WE HAD A FUCKIN' BLAST! Didn't even see it coming either. wOOT! Just wish we had costumes....
