The ship is beautiful. The cabin is luxurious. The food was great and the entertainment above average.
The Infinite Balcony is a gimmick that I consider a TOTAL FAIL.
I am an early riser while my wife likes to sleep a bit later. It was impossible for me to have a cup of coffee on the balcony because of the high noise factor in converting from the extended (closed balcony) configuration to the open balcony configuration. Basically we ended up keeping the window closed at all times and effectively ended up with a very expensive ocean view cabin.
Loved the cabin but hated the infinite balcony.
