We've stayed in the Casades at that particular Vistana. Our friends stayed in the Lakes. The Fountains are some of the older units. Pretty dated when we saw them a few years ago. That may have change if they have done a major renovation in the last few years. The Casacades are the newest units and were awesome to stay in. I felt like Martha Stewart had decorated them. The amenities at Vistana are very nice. We really enjoyed the pools and sports areas.
