We just completed our Solo/Ensemble Festival for the year. I'm the Chair person of the event. I'm not sure what type of music festival you are hosting but what I have found useful is several jobs need a complete job description on a clip board with a schedule for the event. This keeps things running smoothly and will let the worker know what is expected. Runners, warm-up room monitors, and door monitors find the clipboards essential. I bought ours at a dollar store. Check-in and medals sales also need a job description at their location. Also, many big directional signs are a must. Posting the event schedule in every area is also helpful. Hope all goes well!
