In what might be described as a nervous reaction to Marriott’s announcement it was linking its Marriott Rewards program to the Starwood Preferred Guest (SPG) hotel loyalty program, Wyndham announced, then abruptly cancelled a promotion calculated to swoop in and lure SPG members away. Scheduled to run from 12 noon to 11:49 p.m. Eastern Time today, Wyndham Rewards was offering SPG members a one-time, half-day chance to donate their Starpoints to charity and, in return, receive four times those points with Wyndham Rewards, plus a status match. The deal sounded too good to be true since Wyndham was named the top program in a survey conducted by IdeaWorks Company for Switchfly. That survey compared Wyndham Rewards to five other global hotel loyalty programs — SPG included — and found that Wyndham’s program gave customers an average reward payback of $13.60 for every $100 spent. By comparison, SPG’s payback was only $5.60 and Marriott Rewards’ was $9. Wyndham rewarded customers, on average, 146 percent more than SPG, which was ranked last. Well this morning Wyndham cancelled the promotion citing widespread fraud. Which is kind of strange since the promotion was scheduled to begin at noon. We were going to cover the Switchfly survey anyway, so it’s all news to us. To read more about the survey at Travel Skills, click here. To read more about the promotion at Skift, click here.
