My wife and I are meeting with a Cast Member to purchase 200 Direct points for the Grand Floridian on May 20th. Question about use year. Can be back date to a March UY so as to use 2022 years points for this Nov or Dec stay and then bank what might be left over for a longer 2023 stay. We are planning for a late March '23 stay for our wedding anniversary but did not want to wait for that to be our first trip as DVC members, Any suggestions would be appreciated, Thanks
