Since our story was published, Cruise Critic has now included information about its ownership on the site's About Us page.
TripAdvisor has owned cruise review and content site Cruise Critic for over eight years - but casual users would probably never know.
The website has even sat outside of the main offsho0t of subsidiary brands known as the Smarter Travel Media unit, home to AirfareWatchdog, BookingBuddy and others.
As a result, perhaps, it has arguably never really had any of overall look and feel of its family sites and has therefore focused on being solely a solid, heavily used forum-cum-news service for the cruise sector.
But in recent years, as the burgeoning cruise sector has seen the launch of countless new sites which have attempted to capture the eyeballs of high-spending cruise lovers, Cruise Critic has started to (finally) evolve.
Whilst it still doesn't have as many of the user experience bells and whistles of some of its brothers and sisters, there is marked improvement.
The latest addition to its content armoury is an entire channel containing 360-degree panoramic views of cabins and public areas on ships from many operators.
There are now 27,000 photos from six cruise lines, including Holland America, Norwegian, Princess, Royal Caribbean, Carnival and Celebrity.
Although Cruise Critic has noted the provider of the content, it doesn't mention that the "photography specialist" is indeed another TripAdvisor brand: Oyster.
Furthermore, Eytan Seidman, Oyster co-founder and general manager, highlights that the pair "share a common core principle" - but that's around providing information to travellers, not their ownership.
Despite the changes and improvements to the Cruise Critic website, users will still have no idea that TripAdvisor is the parent company (it doesn't even mention it in its About Us page).
Meanwhile, TripAdvisor appears to have abandoned attempts to sell the CabinGuru domain name.
The company put the URL up for sale via Sedo in March 2013, but presumably didn't receive any worthwhile offers as its later renewed the lease in June 2014 for another two years.
