Following this basic guideline will keep you alive through the convention, maximize your time for gaming, and allow for the comfort of those with whom you are gaming. Please, please, please take a shower and use deodorant, folks. Oh, and no matter what you think, cologne/perfume cannot and does not make up for the lack of showering.
And here, to put the whole showering thing into perspective, is Savage Gypsy:
That said, given that the fourth wave of the COVID-19 pandemic is among us, it's important for those physically attending the convention, regardless of whether you're vaccinated or not (but especially if not, and if not, WHY are you going to attend that convention??!!), to wear a mask, practice social distancing when possible, and keep washing your hands. The protocols for COVID-19 are there for a reason in these difficult times.
Finally, for those attending the convention... Have a good time, but... Stay safe, and stay healthy.
