Chuck.. I can't help with your cabin assignment question. But I had the pleasure of sailing the Nieuw Amsterdam out of the shipyard in Italy prior to her Inaugaration, and then be present for her naming in Venice, Italy.
Here's a link to my original live blog, and at the end there are links to other pieces I wrote from the ship, as well as lots of photos.

I loved the ship. She's truly beautiful, with lots of sophisticated touches. You two should have a WONDERFUl cruise!
