TUG is a great site, but be aware, that most of the people who visit that site are used to "traditional" timeshares. If you are interested in trading
DVC points for some other resort, I would suggest phrasing any advert that you may purchase be in terms that people used to "traditional" timeshare would understand (because they aren't going to have a clue probably what a "point" is worth), for example:
Willing to trade one red week 2BR unit at Disney's Old Key West Resort during September thru November (not including turkey-day week), for equiv accomodations at RCI Gold Crown Resort in Carribean during same time period.
Most timeshare people are used to weeks which run Saturday to Saturday or Sunday to Sunday (though you occasionally see Friday to Friday) - the advantage you have is that you can be as flexible as you want, but that's the type of stuff you will typically be offered.
Generally, I would call virtually all weeks at a WDW DVC resort at least red weeks, and obviously the prime seasons are going to be really bright red weeks. No blue or white weeks here!
Also, be sure to use the TUG resort reviews/ratings so that you know exactly what it is you want and what you would be getting if someone makes an offer. RCI and II have different rating criteria, so the reviews on resorts from TUG members can really help in determining if it's really a resort you might want to stay at. For example, we own at an RCI Resort of International Distinction (RID), it's a very nice resort, but the main reason it's an RID resort is because there are only 3 timeshare resorts in this town, not necessarily because of the resort amenities. Likewise I know of an RCI Gold Crown Resort (supposedly top of the line) that again, is mainly GC because of location (actually, the only thing that made it a GC rather than an RID was that they put in a pool).
When reading member reviews, keep in mind that sometimes the resort reviews are kindof like the room reports that this site used to have; you may have to take them with a grain of salt and look at the overall feel of all reports rather than focus on a specific one.
