I know SPG matches your Marriott rewards level when the accounts are linked. Currently I'm gold on MR through what appears to be an automatically generated status challenge, and will be platinum in a few stays. I'm at 38 nights on the year right now. I'm only currently showing as preferred guest plus though on SPG's site even though I'm gold on MR. Does SPG look at MR nights and not status to determine SPG status? Likewise, I'll be on MR Platinum early, so will that transfer to an SPG status match of platinum or will it only hit when I get 75 actual nights with MR?
Thanks in advance for the help!
