Yes. I probably average around 15 paid stays per year on businesss and have been Platinum for around 3 of the past 6 years....mainly due to promotions and credit card points. Now that these don't count towards status, combined with the increase in points required for reward nights in good locations, it doesn't make sense anymore. I'll see out this year with Platinum status and then move on to Premier Inns and laterooms.com bookings. Won't bother with another hotel loyalty scheme as PC was the only one that worked considering my relatively low hotel stay frequency.
I know IHG won't miss my 15 paid nights, but I think there are a large number of business and leisure customers who chose IHG hotels because it was the only loyalty scheme that rewarded them for a relatively low stay frequency. I hope they have done their sums properly and know what they are doing....
