If this is a Platinum or Platinum Plus week, this is a fair trade for the 270 points II uses for trade and maybe even for the 296 points OKW will cost for a trade. It is not a great trade if not Platinum or better or for the 350 points a 2 BR would be at the other WDW resorts but still might work for the right person. If you would consider a smaller unit or 6 nights, you may want to post.
You should also know that it is against II's rules to trade an exchange though it is done all the time.
