Vistana has multiple phases and each one is very different from the others. The older sections are 2 stories, Fountains is 3 stories with no elevator, and the Lakes and Cascades sections are 4 to 6 stories with elevators. FWIW, my favorite section is the Lakes. Cascades is the newest, but it is the most crowded. Plus, at Cascades, you can end up in a unit right on Rt 535 which has a great deal of highway noise. One of the reasons we prefer the Lakes is because it is as far away from I4 and 535 as you can get, yet it is close to the Fountains pool and rec area. Let me also say that Vistana is an outstanding resort. You could spend days there and not be sorry you weren't going to a theme park. Several restaurants and many activities. It's a great destination resort.
