I was only uncomfortable at one point when we were in a crowded elevator in the Marriott with some people (maybe 5-6 guys and 1 girl) who were very drunk, loud, and didn't seem like they were there for the con so much as to get wasted in public and be as obnoxious as possible. In general Saturday night had kind of a weird vibe for me ... I heard people were throwing beer bottles down into the Marriott lobby, but didn't see that personally. Other than that, no problems.
