Bongo is correct. You could try to sell the entire contract and then purchase a smaller contract that better suits your current needs. The ability to sell and price will depend a lot on the Home resort and the size of the contract.
If you have 300 pts at BCV, it will probably go pretty quickly. You could then take the proceeds and purchase a 200-pt resale, or whatever number of points you now feel you need. The only financial downside is that you, as the buyer, would pay closing costs on your new contract. And, if you get a broker involved to sell your contract, you will likely pay 10-12% commission.
If you're sitting on 600 VB points, you may be in for a long wait.
