I just got an email "Welcome to the Redesigned Kempinski Discovery". It has links to their website and I haven't figured out the details and differences from the current version of their loyalty program. However, the emphasis seems to be "local discovery" special experiences. The email says that there will be "enhanced" (this word scares me) benefits beyond GHA = Global Hotel Alliance benefits. Benefits include late checkout (no mention of when or if it's guaranteed), room upgrades, early check in, and special deals on restaurants and services.

There will be three tiers (Gold, Platinum, and Black, I guess like AmEx cards), with status determined by GHA nights or total spend during Kempinski stays.
