While this seems to be a targeted offer for select IHG One Rewards members, for now, I have received an email from IHG to pre-register for its first promotion of 2023.
IHG One Rewards Offering Up To 9,000 Bonus Points On Stays

Between January 1, 2023, through February 8, 2023, the IHG reward program is offering members 3,000 bonus points when staying any two nights at any IHG property around the world.
What’s better? You can repeat this a total of three times allowing you to earn up to 9,000 bonus points when staying six nights.

There are some terms and conditions you need to be aware of:
- A registration or ‘pre-registration’ is required in advance in order to be eligible for the bonus points offer.
- Reward Nights or Points & Cash rates are eligible for this offer.
- Bonus points will be posted within 6 weeks after checking out.
Note that this is a targeted offer among IHG members so you can check your email if you received the pre-registration invitation or you can check from the offers page of your IHG account.

How Many Bonus Points Can You Earn
IHG One Rewards has unfortunately capped the bonus points to 9,000 points so if you have a long stay during the promotional period, you could earn up to six night’s stays.
Based on IHG rewards Club Members will earn 10 points per dollar spent at IHG properties, so getting extra 9,000 points will be valuable if staying at hotels with lower rates.
Summary
The IHG One Rewards program just announced its first promotion for 2023 which is exclusively offered to targeted IHG members who received the pre-registration offer by email.
With this offer, select IHG members will be able to earn 3,000 bonus points when staying for every two nights stayed, up to 9,000 bonus points.
