I would agree with Villages. Much newer complex in general with better infrastructure and nicer grounds, IMO. Rooms are nice, just note that Bella (the oldest phase) is not as modern as others even though it was recently renovated. I love the Key West phase because it is in the back and is quiet. St. Augustine is also very nice...more action including a bar for adults and a slide and pirate ship for kids. Also louder and more crowded, however!

Also I don't know if this matters to you, but many of the buildings at Vistana Resort do not have elevators.
