On other timeshare groups, I've read that they are not currently accepting requests due to the current renovations in progress in West Village - not even requests from owners trading their other weeks into OL.
Also, RCI exchangers who trade into OL or OL-West Village may be assigned a unit in any sections through 2007. In 2008, River Island has its own RCI ID# so exchangers will not expect an assigned unit there unless they trade into that section. As of January 2009, each section has its own resort ID#. So after that, you'll know what to expect when you confirm your exchange.
Once the sections are traded independently, IIRC, the "West Village" includes the Tennis Villas and it will have the new Clubhouse, pool area, and restaurant which are now being remodeled and overhauled. "North Village" has Splash Lagoon. "River Island" is self-explanatory.
For your Thanksgiving 2007 trip, you could get anything. Hope you have a wonderful time - people returning recently on the forums have said they did! Enjoy!
