While conventions are great fun to attend as a passive "audience member" as you not only get to network but get tons of free swag, they are a royal nuisance when you are one of the people on the other side of the coin! It's not even the networking aspect which is the worse part (i.e. answering the same darn question ten bazillion times); no, it is all the prep work which goes on behind the scenes which can make it a real nightmare. Out of all the worse parts involved, the prep work of custom flash drives has to be right up there next to "designated driver" on the scut work list of things you do NOT want to be in charge of!
