Hyatt’s World Of Hyatt program has launched the latest promotions where members can receive up to 10,000 bonus points when staying at select properties.
Earn Up To 10,000 Bonus World Of Hyatt Points In Europe, Africa & Middle East

Following Hyatt acquiring Lindner properties and its hotel program ending on July 1, 2023, the World of Hyatt program launched a special promotion for those who are Linder Nights members for an opportunity to earn bonus points.
Through May 31, 2023, the World of Hyatt program is offering a bonus of 1,000 points up to 10,000 points when completing an eligible stay at participating properties in Europe, Africa, or the Middle East.
These promotions require registration in order to receive bonus points. Furthermore, the terms and conditions state that you must be a Lindner Nights member prior to March 1, 2023, but I think it is open for all Hyatt members since I was able to register as well and there were no further notices or changes.

The program capped the maximum limit to 10,000 points however the offer can be combined with the upcoming global bonus promotion that will be starting on March 20, 2023.

Summary
Through May 31, 2023, Lindner Nights members and World of Hyatt members who register for the promotion will receive a bonus of 1,000 points per night for up to 10,000 bonus points when staying at participating properties in Europe, Africa and the Middle East.
Given that some countries have great rates, this is your opportunity to earn extra points for your next stay.
