The famous KatsuCon (really Gaylord National Harbor) Gazebo. Long celebrated in song and story (and lots of pics and videos) this was probably the only time that I saw it not being used for a camera shot. This was 4am, people started lining up to use soon after.
This was the far more common way to see the Gazebo during the con.
These folks were nice enough to let me take a picture of them together, because KatsuCon is about the cosplay and the performance of it, so the camera people, that frame the shots and make them dynamic, are just as important as the cosplayers themselves. But since this outside...
...you really should see more of it. You can see I95 of the upper right, and all those groups are cosplayers and photographers arranging shots with that in the backdrop.
While they prepare in the hotel arboretum to brave the outside for their photoshoots. Yes, this was still inside.
This on the other hand, wasn't one of the more picturesque places to shoot, but that was the line of people to participate in the Marvel cosplayer mass shoot.
Look at all those partying people! Don't you just want to yell at them to wear a mask? Last time any of them got to boogie on down for a while.
