This is a great promotion if you are looking for a long weekend away.
Many of the properties in Europe which I checked did offer some discount, though in some cases it wasn’t much different from the advance purchase rate.
You must book by 29th of March for stays from 19th of March until 29th of May with the exception of Middle East (30th June) and South Korea (31st August)
There are some good deals for Dubai with some of the Ibis style Jumeirah and the Ibis Dubai Mall for really good prices for a pre-Ramadan break or a stop before Umrah. Unfortunately Pullman Zam Zam is not available in this offer (no surprise).
If you combine this with a cheap flight to Dubai with WizzAir you can have an excellent break without breaking the bank.
