Every congregation has its own approach to structuring religious education. You can implement Amazing Grace with any model your congregation uses.
As a leader, you will choose the combination of activities for each session. You know best how to shape the program to fit your congregation's religious education model, the culture of your congregation, the youth in the group, and the time and space allocated for each session.
Do not feel limited to the adaptive and alternate ideas included in Amazing Grace. Add your own to the mix. Do what is best for the youth in your program.
If you are able to choose a space to use for Amazing Grace, look for a room that is large enough to accommodate your group and its activities comfortably. Ideally, youth will be able to move actively without chancing damage to fancy congregational furniture. Also ideally, the space will be free enough from other uses so you can leave posters and youth creations on display from session to session.
