If your timeshare is part of Interval International, the TImeshare trading company, then you may be able to trade. However, DIsney is very selctive on what resorts us DVC memebrs are allowed to trade for and I assume the reverse works the same way. DVC memebrs don't have the entire list of Interval International resorts for trading. Only a select batch of resorts that meet Disney's criteria.
Check with Interval International.
