LUXURY RETREAT
Amazing Hotels: Life Beyond The Lobby, 9pm, BBC2
GILES COREN and Monica Galetti (pictured) visit the ultimate spa — a luxury clinic in the foothills of the Swiss Alps. Guests at the Grand Resort Bad Ragaz sign up for sleep therapy (with a menu of 14 different herb-stuffed pillows), dietary advice and mineral rich thermal waters, aka ‘blue gold’, piped from an ancient gorge — and a night in a suite will set you back £10,000.
