Question about the Marriott LNF. I got a successful LNF for 2 rooms. One of the rooms matched was 650 from 857. But the final price of $538.50 doesn't seem to be an additional 25% off the $650. With an additional 25% off it should be $487.50. Is that indeed how it works or is the 25% off some other number or is there something else I'm missing. Secondly is it worth arguing. There are 2 rooms with the other one not reflecting the 25% off either and that is a more expensive room.

Thanks
