As per the T&Cs:

'Hotels may choose to award points for other charges at their discretion.'

This does not mean that you have an entitlement to points because another hotel gives you points. If you get them, be happy, if not, it's their decision. IHG has no authority to intervene, unless they change the T&Cs.

These extra points are considered 'non-qualifying for elite status' unless the hotel incorrectly posts them. In that case, IHG can reverse the status of those points.
