Giles Coren and Monica Galetti fly to the other side of the world to work in one of the world's most luxurious eco resorts on the small island of Tetiaroa in French Polynesia, not too far from Monica's birthplace - Samoa. 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. Infused with Brando's environmental ethos, the resort is now one of the favourite hideaway destinations for the rich and famous - from Pippa Middleton to Leonardo di Caprio and Barack Obama.

Monica Galetti and Giles Coren head to the foothills of the Swiss Alps to experience a very different type of travel - health and wellness tourism. This luxury hotel houses not only multiple restaurants, spas and golf courses but also Olympic-standard sports facilities - and a high-spec clinic boasting 80 medical staff, who offer guests everything from sleep therapy to dietary advice and surgery. Grand Resort Bad Ragaz lies in the shadow of an ancient gorge, the thermal waters of which have lured visitors for centuries.
