Secrets of the World's Most Expensive Cruise Ship

This series goes behind the scenes to reveal the secrets of the floating six-star hotel the Seven Seas Explorer. Can the crew deliver perfection to guests with the highest expectations?

Time is ticking away until the maiden voyage.

The Seven Seas Explorer prepares to leave Southampton on a cruise around the Baltics, but as 700 new guests board the vessel various challenges await the crew as the terrible British weather threatens to scupper the lavish Sail Away Party. Every Sunday at sea, the Explorer puts on a spectacular no-expenses-spared Sea Day Brunch, though after a rocky start it remains to be seen whether it will meet the expectations of the demanding guests. Meanwhile, there's is a first in the 20-year career of cruise director John, as he receives a special invitation from the guests of the £8,000-a-night Regent Suite.

The Seven Seas Explorer heads to St Petersburg in Russia, the most popular destination of the Baltic cruise. While guests are away on land, the cleaning team works in full force, facing one of the most important jobs - cleaning the giant 6,000 crystal chandelier in the atrium. Meanwhile, a new butler starts on board and it remains to be seen how long it will take for him to find his sea legs. Towards the end of the trip, cruise director John takes a huge gamble after being called into action to find replacement entertainment.
