Hyatt Faster Free Night with MasterCard is back, starting September 1.

This means that if you stay at two different hyatts worldwide, you can stay at ANY hyatt free. So, if you stay at, for example, 2 hyatts in mid america for $100 per night, you can use your free night for a stay at the Churchill in london (usually£360/nt)
or perhaps tha park hyatt paris (usually 600 euros/nt)

I wanted to mention it on this forum as i missed out on this super offer last year, and thought that i probably wasnt the only one, this is the best hotel offer i have come across ever...
