We went to the Frozen sing-a-long Monday and had a FP+. However, we were OK with it being one of our 3, otherwise I don't think it would be necessary. We were sitting kind of far back, and I don't think the people sitting next to us had a FP+. However, right now it's not that busy. I remember stopping and asking directions on the way, then another family heard me and said to the CM, "You mean the Frozen sing-a-long is STILL going on?" Based on that comment, I wonder if attendance was down a little, as people assumed it had ended. Maybe by November, the word will be out that the saint-a-long's still going on and attendance will be back up.
