Got to experience it all!
...Actually, it really isn't possible for anyone to experience *all* of any con (it's a feat that would even give Hermoine Granger a run for her money). Having said that, I can say from firsthand experience that you experience
far more of a con by attending in person as compared to watching Youtube videos. Lupus in Tabula moments from MFF, for instance, almost never make their way there. Moreover, there really isn't any comparison when it comes to getting to see friends in person.
