Here is the answer I got from my travel agent who said she gets regular updates from Carnival on the cruises she has booked. And I quote:
"The ship is getting an "oil change" and "rotating tires". Just the usual routine maintenance. It is also being given the upgrade for the bedding........oooooohhhh....the Carnival Comfort Bed. It has 600 count, Egyptian cotton sheets and comforters. WOW, I love the beds on Carnival!"
I guess thay are not using those 4" hard foam rubber mattresses and sandpaper sheets anymore. Well shoot, there's one less thing for me to pick on. I don't think Carnival has ever been accused of being comfortable. Just what exactly is Egyptian Cotton anyway?
