It sounds like the water parks are being done last on all of the ships and that it will come in 2009 for the Fascination. But, you never know, things change.
I've never sailed her but was on her sister, the Fantasy back in 2002. They are great ships.
I think overall I probably enjoy RCI a little more but I've mostly sailed Carnival since they generally are a little more affordable.
