Marriott International has launched three promotions across its trio of linked loyalty schemes: Marriott Rewards, SPG and The Ritz-Carlton Rewards.

The Marriott Rewards Mega Bonus Infinite Points promotion means members can earn up to 4,000 bonus points per stay. Guests will receive 2,000 bonus points on their second stay, plus an additional 2,000 points for each new brand they try.

The Ritz-Carlton Rewards Summer Sojourns will give members double Ritz-Carlton bonus points for stays longer than two nights.

Finally, the SPG Take Three offer will see weekend stays rack up triple Starpoints, with weekday stays earning double.

Members must register for each promotion individually by August 30 and specific terms and conditions for each programme apply.

The earning period starts from May 27 until September 4, 2017.

Since Marriott’s acquisition of Starwood last year, members of the programmes have been able to link their accounts to get┬ábenefits such as instant elite status matching and unlimited points transfers between accounts.
