Points plus cash booking is seldom a good idea. However, at times, points and cash can offer excellent value for longer stays. Even better if there is a sale on such bookings.
For 7 days, IHG is offering a discount of 15% on the cash portion of points plus cash bookings.
You can view and book the sale rates on the promotion page.
You need to book by July 19th, 2023, for stays until 31st August 2023. The 15% discount is offered at the time of booking and only applies to the cash portion of the booking.
Note that when you cancel a points plus cash booking, you get your refund in points only. There is no cash refund. In effect, you are just purchasing the points you are falling short of during a points plus cash booking. Fortunately, the cash portion for such bookings with IHG is generally very reasonable.
