Everyone likes what they like. Different strokes...
I've already seen every show on Wonder and wasn't going to ever see Tap Factory, Voices, or Effectors again so I have nothing to lose with a headliner. We loved the ice show and I don't mind seeing aqua shows more than once if there's nothing else we want to do.
I'm not a huge theater show guy (never go to Broadway shows) so I'm actually looking forward to free time after dinner to go to a game show, listen to music, just have drinks, eat more food (I'd do this part regardless, lol), etc. Sorry you're disappointed that there may be one less show to see but I'm sure you'll find something to do in its place.
