For starters my room had a ton of issues, first we couldn't get in, then there were hobo pants in the room we got, room service sucked majorly!, and the shower was possessed by Satan I swear..
To go into further issues, my 3d Gear randomly broke before my shoot, I got the pleasure of frantically fixing that quickly. The con itself while the people were nice had terrible planning and my panel that had no response, until finally I got a response 4 hours before it's starting time.
For a Katsucon 20 it was bad in a sense of con planning, no pulling out tricks to celebrate 20 years, nothing.
The good part about Katsu was simply seeing my friends and doing photoshoots and the artist alley. I felt rather overwhelmed with all the character shoots that took up a ton of my time. But I spent the majority of the time with friends so I was all good.
Honestly I'm going to go back to Katsu again probably next year, I'm just very meh on it at the moment. Maybe I'll try MAGfest or Anime Boston as a winter con next year instead of Katsucon. I just don't know at the moment. :S
