Nice to know there are people out there who agree with me about New Wine. I've never been to the festival, but know a lot of people involved.
If you feel safe and secure in your own faith and belief there isn't a lot of harm you can come to at New Wine. You can enjoy the singing worship and pick the bits out of the talks and presentations without having to subscribe to the view that the only, the ONLY, way to respond to God is to go down the front and get ministered to by someone who will pray for you to have more Holy Spirit. I tended to pray quietly for a few moments and then slink off. I do not join the ministry team because I don't think that is what I understand by ministry.
