Be aware that availability of FFNs changes quickly and often. I tried to book a 4-night FFN stay at Gainey Ranch and got the 'unavailable' message, but was able at that time to get the first two nights. A couple weeks later the 4th night I wanted became available, and last week the missing 3rd night showed up and lasted only a day. Don't know how they'll react to my having multiple reservations for the same stay, but I figure the worst that can happen is that they'll ask us to move from one room to another at some point. Maybe, though, I'll get lucky and once they realize it's a four-nighter I'll get a nice upgrade at checkin.
