The hotel’s Rosewood Mini Hamper is an actual 1993 red convertible Mini that is driving around the capital to raise awareness and is filled with oversized candy canes, large Christmas presents, giant gingerbread cookies and usually, Santa.

Anyone who spots the car is encouraged to take photographs and post on Twitter and Instagram using #RosewoodMiniHamper, with the chance to win a five-night stay at any Rosewood property around the world including return business class flights for two.

It also comes with all sorts of goodies worth £60,000, with the whole lot being auctioned to raise money for the charity.

Silent auction bids start at £18,000 and the “hamper” includes the Mini itself; a weekend stay in Rosewood London’s Manor House Suite with butler service, a spa treatment, dinner and transfers for two; a weekend stay in one of Rosewood Castiglion del Bosco’s villas in Tuscany including return flights from London for two; two tickets to The Weinstein Company’s exclusive annual BAFTA party; a dress by designer Louise Kennedy; a silk dressing gown by Turnbull & Asser; a Perrier Jouët 1999 Belle Epoque Jeroboam; a case of Perrier Jouët Rose 2004; and the selection of sweets, gingerbread cookies, candy canes and cakes.

The hotel also has several Christmas menus and events and Rosewood’s slow food and living market has a Christmas theme, featuring more than 30 festive-themed stalls - a private fireworks display will also take place in the hotel’s courtyard on New Year’s Eve.

Rosewood has also negotiated exclusive use of the Royal Opera Box at the Royal Opera House on December 19 for a matinee performance of The Nutcracker, with a package including a backstage tour, access to the curtain calls at the end of the performance and a three-course meal served in the Royal Retiring Room either pre- during or post performance (package is £9,995).

Guests staying for three nights in either a room or suite over Christmas can have a Christmas tree delivered to their room with decorations provided to dress the tree. The Christmas package also includes dinner in the Mirror Room on Christmas Eve, a gift-packed stocking on Christmas Day, chauffeured Range Rover on Boxing Day to Regents Park for a walk with the hotel’s resident Golden Retriever, Pearl, and a butler service to prepare drinks for the return (from £2,400 for a three-night stay in a room; or £4,500 in a suite).
