Are FP+ needed for the Frozen Sing Along?

We don't normally go for FP+ on shows/events like this but since it's Frozen and since DHS has fewer things to do, is this becoming a greater necessity?

Thanks, I'm always a little uncertain thanks to the Frozen craze. I still can't believe people queued for 6 hours for the Anna/Elsa M&G in Norway, or that FP+ for it are as hard to get as 7DMT.
