The layout of where the line was going to be routed had certainly been planned out.. and for the most part.. what was done was pretty much what I thought was the optimal method to be able to fit everyone.. which unfortunately.. did make it like packing you guys in like sardines... that small hallway.. yes.. we had planned to double down.. but totally did not factor.. "oh yeah.. they'll be probably sitting" aspect.. which would take up a little bit more room..

The San Carlos room (though designed to fit like 89 per the fire code.. sign.. thing).. was more close to 150-180 people depending on how crammed the attendees themselves decided to pack themselves in. I didn't force everyone to just scoot up so more people would be stuffy in there... just kinda happened.
With Yuya's line, the numbers we got through were close to 400 people/session... which means yeah.. close to 400 people/hr.
Add that there were two sessions and you got close to 800 people in those 2 hrs. It was also fortunate we were able to start early as well and it certainly relieved the congestion quicker.
With FLOW... it was crammed into one single 2 hour session.. and we only got close to 600 people through. Having 5 people in the group.. and a slightly more opportune chance to socialize.. the pace was significantly slower. You can certainly say I was slightly under prepared when close to 700 or 800+ people showed up to line up and ended up filling even the reserved area I was going to use as overflow..
Definitely the only time when we mathematically underestimated how many people.. as well as not realizing we needed to cap off the line sooner. We wanted to get though closer to 700 people through the line.. (which was about where we capped it off) but the pace was slower than expected, so when we cut off the line.. and reaching the end of their session.. the people that had still been waiting (before we capped off the line).. eventually had to be dispersed... yea.. about 100 people became very sad.. :'(
I FELT SO BAD...

.. but alas.. there was really no way to plan it out perfectly. I don't have much doubts FLOW will be parting ways with Fanime anytime soon, so I'm sure there will be other opportunities in the future for folks who couldn't get their autograph this year.. to get it in the future.
I am grateful people were understanding about the rules and restrictions (i.e. 1 autograph, photo behind the line, etc).. which helped with allowing so many people to get at least the opportunity to get something signed. As mentioned, I am looking into other possible areas (at least for the expected large lines) to have sessions.. but that might sacrifice the small intimate room aspect. I'll certainly keep that in mind and find something that can be a good compromise.
