The Resort is closer to Disney parks than the Villages - by about 2 miles. Both are closest to Hollywood Studios, of the four Disney theme parks. Vistana Resort is about 5 miles from DHS and Vistana Villages is about 7 miles away. It's about 6 miles and 8 miles, respectively, to Epcot; about 7 miles and 9 miles to Animal Kingdom parking; and about 8 and 10 miles to TTC for Magic Kingdom parking.
We've stayed at both a couple of times and both are very good resorts - though we now prefer the newer, smaller Vistana Villages; specifically in the Key West section at the back of the resort.
The cheapest way to rent a timeshare week is usually to find an owner online who rents or if you have a relative of friend who owns a timeshare somewhere and would be willing to make the exchange for you. Other options include ebay, redweek.com or checking the Marketplace classified section of the Timeshare Users group at tug2.net.
