Forgive me for throwing a wet blanket on the festivities here but while this is certainly a way to make sure you have a nice place to stay (ie. more than just a hotel room and 1 bathroom) while at Disney, I fail to see that this is a great deal. I looked into doing this for the last week in February next year (granted this is peak season and we need a 2 bedroom unit) but at that time, a 2 BR unit in Old Key West goes for aproximately 300 points. The going rate on the DVC rent/trade board appears to be $10 per point thus I would be paying $3000.00 for a 1 week stay in 2 BR unit at Old Key West in February, which is about $428.50 per night. Not exactly a bargain in my mind, especially when you can find some nice properties with 2 BR units off-site for $100.00 per night. I was even able to rent a 3 BR house with a heated pool a couple of years ago about 10 minutes from Disney for $750 for the week. Now I understand that many people miss the "Disney Magic" by staying off-site but is it really worth an extra $300 per night to stay on-site?
Now, if you compare the price of having 2 BR and 2 baths plus a full kitchen and living room on Disney property to the price of just a room at one of the deluxe resorts (Poly, GF, Contemp, Yacht and Beach) which will go for $300-$400 per night at that time, then this option does make more sense. It may also make more sense if you are looking to rent a studio in January (especially if you stay midweek and avoid the weekend which costs more points) but other than that, this just doesn't seem to be a great value to me unless you know of a way to pay less than $10 per point.
Just my 2 cents.
