Wyndham Rewards members can earn 8,000 bonus points, enough for a free night's stay, on completion of a second hotel stay.
In order to qualify, members must begin their stays at any of nearly 7,000 participating hotels worldwide by June 30 and check-out by July 7.
Bonus points can be achieved three times during the promotion period — for the second, third and fourth stays — earning enough for three free nights.
Members can spend their points on rewards available on the Wyndham Rewards redemption platform. The number of points required for a one night hotel stay will depend on the tier of hotel; the minimum number of points required for a one night stay is 5,500.
One qualified stay includes all consecutive nights at the same participating hotel, regardless of check-ins or check-outs.
Residents of the US, Canada, and "any country in the Asia-Pacific region" are not eligible to take part in the promotion.
