first off i just want to say rtx 2018 was an absolute amazing event and i had the time of my life. that being said autograph sessions i have a bit of criticism with. i had a session with arryn and kara on Friday which was scheduled for 12 to 1:30. i got in line after i got out of the RT store on the show floor which was around 11:45. i knew i was going to be hit with a line since i was getting in line 15 min before the scheduled start time but not expecting a line that stretched almost all the way to the entrance to hall 1 in the ACC. once in line the pace at which the line was moving is was easily compared to an assassin snail lol. i didnt enter the ballroom till around 1:20 and once i did the ballroom was very empty with A LOT of space and there was still a ton of people behind me for the 12-1:30 time slot(hopefully they still all got to their sessions even if it was past 1:30 but i get the feeling that they probably didnt). once inside though i was there for maybe 5 min and was in and out. maybe the issue with autograph line length/pace outside the ballroom got resolved later on during the convention. but for me getting in line before the scheduled time and almost missing the scheduled time for autographs was unfortunate my least favorite experience this year. maybe the issue was that there was only one security check point to get into the ballroom but if we have to go through security check points to get into the ACC to begin with what was the point of having another one to get into the ballroom and slow down the line.
