Sandy, I think Cruise Dad is referring to the outdoor ice rink they put on the NCL EPIC. It was a mobile ice floor that had to be put in place every day. It was only used for a few hours (which had little use), and then taken back up so the space could be used for other activities. When President of NCL, Kevin Sheehan went under cover he found out the hard work it took to put the ice rink in place for such little use. He had it removed from the ship.
Cruise Dad, In 2004 Carnival's then President, Bob Dickinson, did go under cover on his own on the Carnival Imagination. He worked in several different positions and as a result made several changes that made the quality of life for crew better. Many things have changed with the company since he retired a few years ago. Some good, some not so good.
