If you reside in China, Hong Kong, Macau or Taiwan and are planning a weekend getaway in one of these places, IHG Greater China Staycation Offer can save you a lot. You need to be an elite member to avail the offer. i.e. Gold, Platinum or Spire. The offer page does mention Intercontinental Ambassadors but they anyway get a elite status so that's kind of redundant. If you are not an elite member, you an always buy an elite membership if the overall savings seem to be worth it.

You also get 4pm late checkout, subject to availability. The offer is applicable on the "Best Flexible Room Rate with Breakfast". This offer is applicable on weekend stays between July 15, 2019 and July 19, 2020 (including Friday, Saturday, and Sunday nights, but excluding public holidays),
