Guests who book a three-night stay at a Dorchester Collection hotel will receive the third night for free until the end of March.
The "stay an extra night on us" promotion is available on selected suites and rooms at all ten of the group's properties.
The rate is based on double occupancy, while should the reservation be changed so it is no longer three consecutive nights then the charge will become the best available rate at the time of amendment.
Helen Smith, vice president of sales and marketing for the Dorchester Collection, said: "The additional complimentary night is exceptional added value for guests wanting longer to enjoy the various hotel offerings throughout the collection, including award-winning spa facilities and restaurants, whilst having more time to discover the destination."
The offer is valid for stays until March 31.
