Many of us own both II properties and DVC. There are trades to be had to DVC but not that many. Not enough to justify buying elsewhere to trade in certainly. Most trades are available Adventure, Choice and Dream seasons. Occasionally Magic Season is available but never Premier time. That means that most trades are to be had Jan, Feb, May, Sept and Oct. II charges an extra $95 fee in addition to the regular trading fee. Many units come available only a few months before the travel so if air fare is an issue that might not work out well.
