That's why I also mentioned seating areas. "Hey, can I sit next to you?" is an easy way to start a chat with someone because if they say no you never had a chance of talking to them anyway.

Two things to remember:
>You will get out what you put into a conversation
>Most people love talking about themselves

Ask questions that can't be answered with yes/no. If they're giving short responses anyway, offer your own input on their answer before leading into a probing question for more detail. If you ask how long their cosplay took and they say six months, you could say
>Wow, that's a long time. What part of it took the longest to do?
Rinse and repeat. If they answer a question with something you disagree with e.g. liking Naruto, you bite your tongue on the judgement, acknolwedge the validity of their view, and mention your own as a preference rather than a superior position.

After a bit of this you'll have some confidence with your rapport. Especially if they're asking you things too. Here's where you ask for socials - ideally for the purpose of scheduling a meetup the next day of the con - but that might not always be possible. Point is to at least make it clear you'd like to hang out with them at some point which is why you're asking for their info. If it's gone particuraly well you could ask to tag along with them then and there too

Ganbare your best anon!
