I am now in similar situation. I have 25 points (June) and 200 points (August), all at WL BR, just closed on the 200, sold our old June BCV contract. I think it will not be TOO bad to deal with. I have applied the first 25 (2017) and second 25 (2018) already, to a trip in June this year. I may use them like that, for first night of a split stay, or something.
The other option is transferring the 25 to the contract with the 200, but I have no idea how to do that. I will worry about that in 2019. I am ok dealing with the 2 use years, because one is only 25 points, and I go 2-3X a year to the parks. It was worth it to US, to get a loaded resale contract, with 2017 points, and 2018 coming in a few months.
