Marriott International has launched the first joint loyalty promotion covering its Marriott Rewards, Ritz-Carlton Rewards and Starwood SPG schemes.

Marriott says that “For the first time, the three programmes are offering the same promotional opportunity, giving members the chance to earn double points on their first three stays at participating hotels in each programme”.

To clarify, this means that members can earn double points on their first three stays with Starwood SPG (at participating Starwood properties), and double points on their first three stays with either Marriott Rewards or Ritz-Carlton Rewards (these last two are effectively the same scheme, marketed under two names), at participating Marriott properties.

The offer follows the recent merger of Marriott International and Starwood Hotels and Resorts, and the subsequent ability to link loyalty accounts, match status and transfer points between the schemes.

This effectively means customers who are members of both the Starwood SPG, and either the Marriott Rewards or Ritz-Carlton Rewards programmes can get double points on six stays, and then combine the points into one scheme as desired.

Members need to register for each promotion here by March 15, 2017, and complete their stays between January 16 and April 15, 2017.
