When I have had at least 2 months in between trips, I don’t renew and just buy new,
With the way my travel has been, I have been able to stretch 3 APs to cover 5 years of trips.
For example, my AP expired in early August, but I bought new in October instead of renewing so my late August 2020 trip would be covered,
Next year, I will not renew in beginning of October, but buy new in December. Because I just retired and will be going more often, this pattern may be coming to an end. But it has worked well,
In your case, if you can vary a trip by one week, you could make it work. For example, buy new in November 2020 and cover that trip and June 2021, and the go one week earlier in November 2021 on this same pass.
Then you wouldn’t need a new one until June 2022.
