In this Christmas special, Giles and Monica travel to Kulm Hotel, St Moritz. This Swiss Alpine hotel was the birthplace of winter tourism more than 150 years ago. The Kulm's owner, Johannes Badrutt, made a bet with summer guests that if they returned in the winter and didn't enjoy themselves he would pay for their stay. The guests stayed for the season - and a new industry of winter leisure and sports was born.

The Silo is an industrial-chic, luxury art-themed hotel in the heart of Cape Town. It sits in the former elevator shaft of a 90-year-old, 187-foot grain silo (once dubbed the tallest building in sub-Saharan Africa) and on top of the new Zeitz Museum of Contemporary Art Africa - the African equivalent of the Tate Modern - within the same re-purposed historic building.

With the help of hotel historian, Fintan, Giles discovers that the castle has had a rollercoaster journey through the centuries, sporadically reaching moments of real jeopardy, only to be saved by a turn of events or new owners. As recently as 2011, the hotel went into receivership but was bought in the nick of time and, after undergoing a ú50 million restoration, has the ambition to be the best hotel in the world.

Led by the hotel's mountain guru Maher, Giles and Monica undertake a test-run of the stunning adventure course before it opens to guests, facing 30-metre drops and Giles's prolific fear of heights.

Here, surrounded by a beautiful coral reef and an abundance of marine life, they both work alongside the staff of the exclusive Brando Resort to serve 5-star luxury to guests paying up to an eye-watering ú11,000 per a night. The hotel was the brainchild of Hollywood star Marlon Brando, who wanted to preserve Polynesian culture and marine life - and Giles meets Tumi, Brando's granddaughter, who strives to deliver his vision.

Giles and Monica experience the warm embrace of Fogo Island Inn on a rocky, sea-sprayed outpost of remote Fogo Island in Newfoundland. White, angular and perched atop zig-zagged stilts like the local fishermen's houses, it pays homage to the European settlers that arrived from Ireland and Devon to fish cod. A cod-fishing moratorium was put in place in the 1990s, and the island's population subsequently shrank as families moved away in search of other work. Giles and Monica meet founder Zita Cobb. Her family has lovingly folded its rich heritage into a unique retreat for guests from all over the world.

In contrast to the developing country it inhabits, the 'jewel of the city' was built with a limitless budget by royal decree to showcase the kingdom to world leaders and to billionaire and celebrity guests. Its network of luxurious riads, built by the nation's finest artisans, are kitted out with suede and silk carpets, extravagant chandeliers and open fireplaces lit by personal butlers. The hotel prides itself on its incredible attention to detail, creating an absolutely flawless guest experience. Monica works with executive housekeeper Laurence, who intriguingly teaches her to how to 'show love to curtains'.
