There are two types of Wyndham point packages. 1. The converted to points fixed week. These are mostly from the older resorts. The owners can only book their particular weeks during the 13 month advanced reservation priority period. 2. UDI (undivided interest) points - a resort is worth so many UDI points, say one million, and each contract/deed is so many points or percentage of that one million. These are backed by deeds and are mostly at the newer resorts, but I have seen some at older resorts for small amounts like 49,000 or 28,000 points that were sold as add on bonuses. With the UDI points you can book any week or unit at your home/deeded resort at the 13 month advanced reservation period. So this means that if all the owners of a particular UDI resort want 4th of July week, then there will be some stiff competition to get it and not all owners will be happy campers.
Our last Wyndham purchase was several years ago and I am a bit out of the loop, but I also think, from what I have been reading, that there may be an additional type called "Club Wyndham" which has no home resort and you don't get a deed, but ownership in a trust that owns the deeds (maybe similiar to Worldmark or Bluegreen), but others can explain more about that.
