Nana, yes, there have been some problems reported on cc lately about the Navigator (I've read them just like you), some of them links to rather dubious sources, unfortunately. I also have four cruises on this ship, in 2000, 2001, 2005, and 2008. Most of the problems in the reviews you mentioned have been mechanical. Personally, I have been very lucky and had no cabin problems, but there have been a couple of them reported to me from friends. I am certain (I am an optimist, yes) that these issues will be taken care of in dry dock.

Most of my Navigator cruises included my favorite itineraries (Alaska, Baltics, and Norway) ever on a ship, so it holds special memories for me.

I think the main thing, if it has to do with ANY dissatisfaction you have, is that you report this immediately to the manager in charge of that area on the ship right away. They will surely try to resolve it. I am eager to return to the Navigator one of these days after the dry dock, as I'm sort of "booked up" until after it comes out!
