Ok, I don't know anything about Fairbanks outhouses! You're definitely not getting those with points. We were there last summer for 2 weeks and tried to use points as much as possible. I got 5 free nights in Anchorage (1 the night we arrived, then 2 Shabbosim in Marriott next door to Chabad), 2 in Seward, and 1 in Fairbanks.
The night we were in Fairbanks there was supposed to be a chance to see the Aurora, so I looked online to find the best place to go and drove out at midnight to what felt like the middle of nowhere. I pulled up in total darkness to find ... an RV full of Japanese tourists who'd been camped there for 3 days! And it was cloudy that night and no Aurora.
While there check out the Ice Museum (the one in Chena gets better reviews, but it's a long drive, and we enjoyed the one in Fairbanks, esp. the real ice slide with a sled you can go down), and you must go to the Antique Car Museum - it's an absolutely amazing collection! If you like museums, Museum of the North is good, as is the Thompson Visitor Center (free). Pioneer Park is a tourist trap.
