On Holland America's Maasdam, on our honeymoon, we met many other honeymooning couples at a Captain's Cocktail party, and were invited by one of them to their #1 Penthouse Suite. I have never seen anything like it before or since, and probably never will, unless of course, as a visitor again. Nice to see how the "other half" lives! Me, I'm happy with my little balcony cabin. Or not, just a cabin on any cruise ship would make me happy!
