Renting points are the way go. Could save you up to 40% off of Disney's rack rates. Check our Rental/Trade board, or check EBay for current listing.
Assuming your check-in date is 3/1, and check-out date is 3/7(that would be six nights accomodations), you'd need to rent 275 points. The point requirements are 75 pts/night on Fridays & Saturdays(3/1, your check-in day, is a Saturday), and 40 pts/night Sunday-Thursday. Since March is so close, I think that $7-$10/point(depending on the renters use year)would be a realistic starting point to calculate your cost. You'd be looking at $1925 on the low end for a 2Br for those nights, or slightly less or more depending on the deal you and the renter work out and how soon the points expire. What would happen is the renter, the person you're renting points from, would call Disney to see of the dates are available. Assuming they are, and you both agree on a price, you would then pay in full once the reservation is made in your name. You could request a confirmation from Disney at that point for your records...something in writing that you could bring with you at check-in(just for peace of mind). Typically the reservation cannot be cancelled at that point without you risking losing your $$, unless you work out some sort of agreement in advance.
I think 2Brs rent for somehwere around $500/night, so you can see that the savings are substantial. If you decide to go this route, make your post on the rental board ASAP. And don't forget to check EBay.
