I spoke to a manager at InterContinental Doha at the end of last month as to when or if IHG would bring Six Senses onto the IHG platform, and he told me that IHG plans on keeping Six Senses distanced from the main portfolio for the time being. I wonder when Six Senses might, or ever, join IHG Rewards. Following their pathetically lazy rebranding effort [have you seen their updated app? Wow. Just replaced the orange logo with the new one and that's it. No Apple Wallet functionality, no new look, nothing. Makes me wonder why they bothered in the first place.], I was hoping to see some integration but it's still crickets so far.
