The hotel has a habit of turning the air conditioning on and off at random. Which really sucks, I'll definitely agree about that. I work in Tabletop Gaming which is right next to Video Gaming and let me tell you, it's so much fun having the temperature randomly change 20 degrees in the span of 5 minutes...
Hi! I'm the Tabletop Gaming ADH. I don't deal with the card games at all (I handle the board gaming/tabletop stuff), but I can field this. Or I'll attempt to do so, anyway.
Unless a tournament is being run by a staffer at that moment, there are generally not staffers in the CCG room. We simply don't have the bodies - especially with CCG, which was down a staffer at the last minute this year - to keep someone just chilling in that room at all times. If you had stepped into Florence, which was the main TTG room and my office for the weekend, we had three binders with copies of our schedules and descriptions of everything, as well as several copies of the small program book that you could have looked at. I more or less did not leave that room during the con except to get food and sleep, and I directed many people to the CCG tournaments. About the only question I had about them that I was unable to answer was about signups, but even that I got an answer for quickly
As for the tournament times...the longest CCG tournament was in fact scheduled to start in the morning on Saturday - that would be the 128 seat booster draft. That ended up running over (both because of the size and the fact that it was officially sanctioned, which slowed down getting it started), which may have effected the time that the Legacy tournament was scheduled to begin, as that was supposed to start at 9pm. There are only so many tournaments that can be run during the weekend, though, and there is only so much space. CCG gets the largest room that we have, if I remember correctly, as well as filling a decent chunk in the convention center. There's really not much we can do about that. In order to run the tournaments we want to run, we'll have to schedule some later in the day to be able to accommodate them, and the ones that we expect to be shorter/smaller are the ones scheduled later on in the day.
And also do keep in mind that TTG is a 24 hour department We like to have things going for the attendees from convention start to convention end.
