I also had the expiration in October 2016 and have just renewed on the website for $200.
I'm a bit concerned: the credit card billing went through, but the email I got from IHG was -- empty. And I still have the option to "Renew now" in my account.
Did anyone experience this? I'll wait for a couple of days, then I'll get in contact with IHG if necessary.
