I applaud the efficiency of the Program staff; the only thing I wish they'd done that they didn't was to make sure every panel had a moderator clearly marked. On both of mine with no listed moderator, someone stepped in (me, in one case), but that means the panel is less well-thought-out ahead of time. Assigning someone, anyone, is better than assigning no one.
Overall, the con had a relaxed, fun tone and everyone I saw was good-natured about the various hotel problems that occurred. I was, too.
