I think the "new" deck plans - with effective date 2 april 2012 - are meant to show the "new" Concierge class and do show the re-grading of a lot of suites... the former (single) deck plan did reflect showers being installed instead of baths (ugh!) in many of the suites and that was to be effective 17 April this year. So I assume the showers are in place.

I started a thread on another site asking someone on board to report on the changes but so far, no answer. Either there are no CCers on board OR people are so dazzled by the changes they are not reading the boards!! Eventually someone will answer, I suppose.
