Opus is incredibly flexible in terms of both creative and content offerings. I have never had anyone try to micromanage my own event, so I don't know what that would be like. But if they do, just make sure you understand their point of view. The people at Opus are great to work with, very professional, and will always listen to your ideas (and then come back to you and say "No!" when the time comes to execute). They also make really good decisions about their budget (as long as you know how much money you can spend before it's too late - which you'll know in advance). I'm looking for them to help me with my next three or four events, but am not yet planning those events myself. Opus came to us and helped us plan our first two events, and we absolutely loved them.
