Vistana is VERY close to Disney. When you turn out of Vistana you are within a few feet of an intersection that puts you directly on the highway that leads to the parks. It takes about 10-15 minutes total depending on which park, to get to the parking lot.
Vistana is gorgeous. Has 7 pools, 8 hot tubs. Very clean, well kept, and lots to do.
Yes, the biggest they have is a 2 bedroom, but some will sleep up to 8 people.
