OK, So we wait.
I am/was SPG Lifetime Gold, and should now be 'Lifetime Gold Elite', but it say that I am only lifetime silver. I am still 'Platinum Elite' for this year, which is something. I have several stays coming up and it would be nice, you know, if everything 'just worked'.
Marriott assured us that SPG lifetime status would carry over, SPG Lifetime Gold => new Marriott 'Lifetime Gold Elite'. What gives? I emailed Marriott support two days ago, but no response.
I agree with the consensus here that website is less useful tan the old SPG site. The 'grid' view in particular, to compare rates and properties.
