Sheraton's Vistana Resort is located in Orlando, Florida. It is very close to Walt Disney World in the Downtown Disney area. I visit Disney World quite frequently and my preference is to stay on Disney property, but Vistana Resort was so close that I did not mind being off property.
Vistana Resort is primarily a timeshare resort, although you can book vacation packages there. If you decide to go on one of the timeshare tours for free tickets or other incentives, be prepared for them to hard sell you and keep you there at least one and a half hours. Be firm when you say you are not interested.
Overall, the resort is well kept and clean. It is on the older side, so everything is not brand new. We stayed in a two bedroom villa and had no complaints. I was so busy at Disney and Universal I never explored the grounds or pool areas.
Be careful not to confuse this resort with the newer Sheraton Vistana Villages, which are located near Sea World.
