Sounds like you've settled in nicely, and are now enjoying the cruise. And it sounds as if someone paid attention to your initial critiques of the "studio lounge", and it's now functioning more like it should.
The pace does sound a bit frantic. Too much to see and do, even on a seven day cruise! You don't get to say that too often.
Every review I've read raves about Blue Man Group and Cirque Dreams and Dinner. Those shows alone are likely to be a reason for people to book this ship.... even if they do have to wash their hands in bed
