Officially, you should get stay credit for 6 nights (the 3rd night free promos are treated as a discount IME and not as an actual free night).

Per the FPC T&C you can only earn stay credit for one room per night, though some people have received stay credit for multiple rooms in the past, however thereŽs a chance FPC will deduct those nights later on (they deducted a few stays consisting of two rooms over half a year later in my case), so you shouldnŽt rely on it.

Personally, IŽd probably sign up one of your family members, add their FPC number to the second res and try to have them qualify for Premier status.

Regarding location: Which of the four Fairmont properties are you talking about?
