I finally saw some pictures of the Cirque Tent on Breakaway and they made at least one improvement, they added a stage - however, what is weird is that I once reported that the Speigel tent on Breakaway is much bigger, but NCL contacted ma and said "no. they are the same size on both ships"
Looking at the deck plans - how can this be? Here is Epic...
And here is Breakaway:
Unless Epic is twice the size the room is bigger on Breakaway.
