August 12 update:
IHG now has a second targeted offer that has a higher cap of 10 bonus elite nights through September 30, 2026. This appears to be aimed at certain corporate customers, although we've seen data points where eligibility may be broader than the terms indicate. Here's a direct link to the registration page to check to see if you're targeted.
Original August 7 post:
IHG is targeting certain members with an offer to earn double elite night credits on eligible paid stays completed by September 29, 2026. There is a maximum of five bonus nights. Only qualifying paid stays of at least $30 before taxes and fees count, so award stays and Points + Cash bookings are excluded. Even if you aren't chasing status with IHG, the extra nights can help you reach Milestone Rewards, which begin at 20 elite nights and include options like bonus points, food and beverage credits, suite upgrades, and lounge access.
