I think there have already been some reports that the laser tag is going away in favor of Spice on Encore. I'd expect it to disappear from Bliss as well, to be replaced with more Vibe space (which matches your assertion AND the work that was done on the Joy, to make the Vibe on all 3 ships very similar). In fact, I'd tend to believe it if Encore loses laser tag as if she doesn't lose it and Bliss does it would leave Encore as the only BA+ ship with LT and NO Spice.
Sure, some variety from ship to ship is appreciated, and there's still some, but was LT really THAT popular?
