Delta has vacation packages for vistana villages. I was able to book my flights and 7 nights at the sheraton vistana villages for 3 people next March for $1400.00. I did this through my local Triple A, you do not have to be a member to use their travel services, but I did join for $60 and got 3 day/2 park passes for the 3 of us for $78 a piece, saved us $26 per person so the membership has already paid for itself, plus I can use my membership many different places and save.
You might want to check Triple A near you!
Good Luck whatever you decide!!
