Seven Seas Explorer features in a Christmas fly on the wall special on Channel 5 on Friday.
Filming took place on the 750-passenger Regent Seven Seas Cruises ship on a Caribbean festive cruise.
The episode follows the head butler preparing the $10,000 per night Regent Suite for a special private cocktail party.
Meanwhile, the senior executive chef prepares a culinary Christmas surprise for the luxury line’s passengers.
The cruise director is filmed swimming with stingrays in the Cayman Islands and on a zipline in Belize.
The Christmas special is a follow-up a four-part ‘World’s Most Expensive Cruise Ship’ series.
