Was talking with friends I've attended many a con with over the years, and we noted that it was great to have the Cosplay "relax" space (especially when you're dressed as 3 Steven Universe characters). In fact, we had an absolute blast cooling off and meeting people.
I was thinking that it may be nice to have a quiet "social space" in general. A room, off the beaten path, with tables and chairs and a general "keep it down" policy of noise, something like con suites but larger. It'd be a good place to go, socialize, and do so in a peaceful environment.
