Just received this via DM from Hyatt
We are only offering Diamond status to SPG Platinum members. SPG Gold, Hilton, Marriott, and IHG (any level) would match to Platinum membership status. Please email a screenshot of your activity page with a competitor (with 1 eligible stay this year) to goldpassport@hyatt.com. We have a lot of requests and expect a 48 hour response time for requests. We will be happy to match your status accordingly. Thanks for choosing Hyatt, welcome back! ^as
