With con crud, another factor is all the foreigners and their foreign germs that your system is not used to. If you are traveling from out of the country I would also avoid tap water because every country has different ways of processing it and different bacteria is present which would be harmless to people that have grown up with it, but might not be good for someone whose system has not built up a tolerance for it.
I've come down with con crud, but not after every con I've been to. The worst for me seemed to be the Vegas con because of the air conditioning in the hotels and the contrast of the extreme heat outside (August) plus everyone smoking everywhere there!
