I am not on Anime Matsuri staff. I have debated this on the con I help with. We don't have a First Aid or Medical staff at our con. We call in professionals to handle our emergencies because it is a Liability issue. Conventions can be held liable for what happens to con attendees being treated by "Medical" staffs. It is sometimes a choice between higher event liability insurance rates or a cool guest. We are also in a hotel. Not all convention centers have "Medical" staffs or nurses, please remember that.
How long did you wait to pick up your Pre-Registration? The lack of maps and schedules are unacceptable for any con.
