That's amazing! I really see no downside to getting a fixed week then, unless you really wanted a precise number of points and don't want to buy the extra 10% of points
I agree with @intamin that there is really no downside to Fixed Weeks. We have a FW at the RIV and we love it!
We don't have to walk/stalk the reservation...it just automatically shows up as booked in our account. Love that!
And at the RIV, over time when resale buyers will be forced to use their resale RIV points at the RIV, we don't want to have a problem booking our preferred week.
Since you don't lose your 10% extra points if you cancel the Fixed Week, this was a no-brainer for us.
There was a chart in the past (can't find it now) that showed that the majority of Fixed Weeks were purchased from Week 47 (Thanksgiving) until Week 52 (New Years).
Since those weeks are also the super busy holiday times at WDW, renting out those points (or that confirmed reservation) should not be a problem...if we don't use our FW for that year.
In fact, we wish that all of our DVC contracts were Fixed Weeks!
Fixed Weeks do popup on resale occasionally, and they go right away.
