IHG is offering a discount of 23% to IHG One Rewards members for stays in Europe. If you are not a member, your discount would be limited to 15%. You can always join IHG One Rewards for free.

You can view and book the promotional rates on the offer page.

The promotion is valid for bookings made until 16th October 2023, for stays between 5th October 2023, and 31st May 2024. Bookings must be made at least 3 days in advance.

This is not a flexible rate. A non-refundable deposit is required in full at the time of booking. Cancellations or changes are not allowed. The offer is not applicable to group bookings.

The sale price is more like 12-15% when compared to other non-refundable rates.

I would not risk booking a non-refundable rate for a 12-15% discount. Unless the stay is not too far away and the plans are confirmed.
