I (PLT) am eligible for 5/15K, but my daughter who has no status is eligible for 3/9K. I think I'd prefer the 3/9 as I might do 9 stays by May 30 but not 15. And why doesn't nights count?
Last month at a Hilton I had 1 stay but 23 nights for over $12K. Wouldn't you think that's what SPG would want.
