InterContinental Hotels: Priority Club & Inter-Continental Ambassador - Looking for Thread concerning stay one night, get the second night free in UK

I saw a thread in this section a couple of months ago concerning a special offer for Holiday Inns in the UK where if you booked one night, you got the second night free.

Unfortunately, I forgot to write down the details of the link concerned and I was wondering if anyone could point me in the right direction to the relevant link.
