I didn't get the choice of 25K or Plat Status for a friend last year nor I got it this year when I renew last month. But please do report back if you do get it
They don't tell you about the 25k bonus any more but it's still there if you look for it.
From memory click on 'Spire Elite' then 'Explore Your Benefits' in your online IHG account and you should be able to claim them - mine are all there from 2015 to 2018
