I just got the official local letter from the good folks at Dragon*Con and Firefly Cargo Bay will be in aisle "E" in the basement of the Marriott hotel. The tables numbers are E27 and E28 but that won't much matter. You just need to find aisle E and then look for the banner with the FFCB logo on it.
SHiny stuff for sale! Big stuff, little stuff, Browncoat stuff, Dr. Who stuff, Whedon stuff, Princess Bride stuff, LOTS of STUFF!
So, 24 days from now, stop in at the 24th Dragon*Con and say Ni Hao!
