I have mixed feelings about this. It signals growth and big is basically a statistic. Better has no correlation. And opinions will always differ.

I steward at Warwick because I like the festival and Dick Dixon has never felt the need to insult me when I voice opinions. He politely disagrees with me or thanks me as appropriate.
But where are the 20,000 people? Busy as the town is the number looks a bit optimistic, even adding the castle and three days together.
