random thoughts ...
We have a fixed week at RR. As noted above, you have to call to make any changes. That means that if you want to swap your week out for points to adjust the dates for your trip, you'll have to do it over the phone, so if you're trying for a super popular week, the delay might be an issue.
We have a small contract to buffer ours since we don't always travel sun-sun either. We bought a contract that was enough points to round up to the next discount level (
DVC allowed us to do that at the time).
I have never been able to call and adjust the dates unless I did it right at 11 months and everything was still available. I also have never been able to shorten the trip if needed without risking losing the reservation when it was being transferred to points. I have tried a few times over the years and have been strongly advised against risking a waitlist picking up the reservation during the process. For this year, we're leaving before the final Sunday and forgoing the points for the last couple of empty nights. I didn't want to risk losing the time during a sold out week. Not efficient, but we're at peace with it.
The reservation always shows up a couple of weeks before the 11 month mark, and honestly it's never occurred to me to try calling
before 11 months to see if I could have the points converted beforehand so they were sitting in my online account for booking right at 11 months. I might call and ask this year as soon as the reservation shows up in my dashboard.
I wouldn't bother with a fixed week for a May week because it's a low demand time of year. I'd always opt for a fixed week for a more popular week (like around thanksgiving) and trade out for May whenever you want.
We're happy with our fixed week, but we too have a week in the fall that's 139 points but only cost us 130 when RR first opened. Maybe I'd feel differently if the adjustment had gone the other way lol. That said, I think I'd always buy a fixed week if I could afford it. We were looking at a fixed week at Poly but the two bedroom is so many points that I think it might be harder to resell such a big contract. Studio FWs seem best (but maybe I'm completely wrong about that).
