Edited to say, I was confused by the Fantasy Faire show and the Sing along Frozen show, sorry! I did not see the Fantasy Faire show.
The Frozen singalong show FP is not connected. Lots of people got one for the show, and then got in the Olaf line to get a beeper (also not connected). This is how it was last week, we were told this by a CM in the Olaf beeper line.
With the Olaf beeper, you do not HAVE to return right away. They said it would only
signal while in the area, From ToT to Animation bldg, but that if you were in a show, or on a ride, or on a line somewhere, not to leave whatever you were doing, to rush back for Olaf. I think the beeper FP setup, is genius.
I thought the Sing along was ok, but not so many people were singing.
It was fun, I thought the way they had one narrator interact with another was a little stiff, but I am not a child, not the intended audience. Kristoff was adorable and got lots of tween shrieks and call outs. I think overall guests would like more from the face characters, less clips, as there was lots of excitement when the characters popped out.
The theatre is nice. Enjoyed the sing along, the Olaf meet/greet, and watching SoCal kids freak out over the snow. (we are from a snow zone, so it was sweet and funny to watch the snow play and sledding)
