If you want to take an online tour I think tagrel.com has a nice website with tours of the DVC properties/pools. Also, Deb Will's site has some great pictures allearsnet.com (just look under accomodations).
I noticed you're from Indianapolis (so are we)! We really enjoy our DVC membership. Our home resorts are VWL, BCV, and BWV. Good luck with your decision on where to buy.
