I doubt it could get worse. Due to the fact they did it by table numbers and not game systems and time slots you had GM's sat round not getting players and players not getting GM's.
Players didn't know that say slot 8024 "Call of Cthulhu 10am Saturday" was full you then had to ask if 8025, 8026, 8027, etc which where the same game with a different GM were also full.
Mind you they shouldn't have to know that. They should have just been able to say I'ld like to play in Call of Cthulhu at 10am Saturday, and the people selling the tickets assign them a table.
As it was the first table could fill up and then people could get turned away. Leaving GM's and players who wanted to play but each thinking the other didn't exist.
This also ment that if someone else volunteered to run a game there was no way of inserting an additional slot into the program at sort notice.
The tickets to the convention were also a step back from pervious years going back to 'transferable' badges that had no way to link them to a particular person. The last couple of years before they had moved to colour coded wrist bands, thus you couldn't switch them between people.
