I just dropped 2 plat free nights last stay at the springs, and a third night free cert at CLL.. I tried to use the 3rd night free, at Kea Lani, but I used one free night plat cert at Kea Lani instead. 7 years, I've never successfully been able to combine a plat free night cert or two, in place of one or two paid nights with a third night free cert.. but I've never called reservations two or three times like some of the other FPCers on FT did. So it is possible.. not by T&C, rather an exception would have to be made with whomever you're talking to at reservations.

Have you ever tried using your free nights at Kea Lani?.. there you get free nights on one bedroom suites without using a suite upgrade cert, basically the best value of all Fairmont properties because Kea Lani is an all-suite hotel.
