It sounds like you're confusing Standard Rates and Standard Rooms. There is a Standard Rate for every category of room and suites. There are other types of rates, too, such as Member Rates, Bed & Breakfast Rates, Double Points, etc. To use a Free Night Award a Standard Room must be available. For example, at the PH Paris-Vendôme the Standard Rooms are either the Park Room King or the 2 Twin Beds. Any other category of room, such as King Bed Deluxe or Family Room, cannot be booked using Free Night Awards. Looking at the dates you mentioned, 9-11 September, there does not appear to be any availability of the Standard Room categories at the PH.
