So if you use it now, you can get around 150$ value, if you wait, you could get much more (if you were planning to spend 4 nights somewhere ofc): it's very surprising but the free night will be applied on the most expensive of the two nights! Let's see if there is some limit to it...
LoyaltyLobby published an article about it and apparently they reached out to Accor. Seems to be that the free night is combinable with any rate and not just the Bar rate.
