I second that! Having worked five Cursillos, I can tell you that it is a huge commitment of time and effort, loss of family time for a weekend, maybe even loss of some vacation days, but without each one of us making that commitment those souls would not experience Cursillo and receive the tools that will help them grow as Christians. And it isn't just the team, it is all the people in the background making it happen. Say YES. You won't regret it!
