At a r convention I heard of, the special guests didn't show up as promised. Fans had paid a lot of money to see them, and there was no prior notice. Everyone was disappointed and angry. They had planned their whole day around meeting those guests, and it all fell apart. It was a nightmare for the attendees who were really looking forward to that experience.
One horror story was when I was at an anime convention and the line for a popular autograph session was so long. People were pushing and shoving. Some even tried to cut in line. It was chaos and I almost got crushed. I felt really scared and frustrated.
One horror story could be about overcrowding. At a furry convention, the venue was way too small for the number of attendees. People were constantly bumping into each other, and it was difficult to move around. Some fursuiters even had their tails or ears accidentally stepped on, which was really painful and ruined their experience.
The lack of proper ventilation is often an issue. The convention halls get really stuffy and hot with all the people. It can make you feel sick after a while. Another thing is that some vendors sell really low - quality Homestuck merchandise. You might think you're getting a cool item, but when you get home and look closer, it's just a cheap knock - off.
One horror story was the overcrowding. There were so many people at the Homestuck convention that it was difficult to move around. Lines for panels and autographs were insanely long. It felt like you could barely breathe in the packed hallways. And the noise level was overwhelming, making it hard to have a normal conversation with fellow fans.
One horror story could be about a guest finding a rat in their room. They were just settling in when they saw it scurrying across the floor. It was so disgusting and made them feel very uncomfortable. They immediately asked to change rooms.
There was a time when the air conditioning broke at an anime convention. It was in the middle of summer, and everyone was sweating buckets in their cosplay costumes. The smell was horrible, and it made the whole experience really uncomfortable. Some people even fainted from the heat. Cosplayers had their makeup running, and it was just a mess.
One horror story is when a cosplayer's expensive and carefully made costume got ruined by someone accidentally spilling a drink on it at the convention. The cosplayer had spent months on it, and it was a real heartbreak.
Sure. One convention horror story I heard was about a cosplayer who had their expensive costume stolen right from the convention hall. They left it in a supposedly secure area for just a few minutes to grab a snack and when they came back, it was gone. Another is that some conventions are so overcrowded that people can't even move around to see the exhibits or meet the guests they want to. It's really frustrating for attendees.
Technical glitches are quite common in convention horror stories. This could be problems with the sound system during a panel or the lighting in an exhibitor's booth. Another is food and beverage problems at the convention. For instance, if there are long lines at the food stalls or the food is of poor quality. And of course, unruly or disrespectful attendees can also be a part of these stories, like people pushing in lines or being rude to cosplayers.
