For us, the extension was a big ordeal, fiasco. First, our guide called and asked if we wanted the extension. We said "No', but then he said that because we'd replied we'd be getting an OKW lithograph. A couple weeks later we received it. Done? Not quite! THEN, another person called us and said we needed to come in and sign, we hadn't responded to the request to extend. When I told her we had the lithograph as proof we'd responded, she said "Some people got lithographs in error, so that must be what happened to you." Since I couldn't convince her we HAD responded to our guide (we were wrong, not
DVC, I guess) we had to take about an hour out of our next trip to go to SSR to sign, which our guide had never mentioned. After all these years, it's still a sore point with us.
