Coralway:
Isolation does seem to contradict The Villages Life Style!
That said, you do not need to be hooked to your neighbors day in and day out! It is important, I think, that you and your neighbors interact on a regular basis. But, you don't necessarly need to be 'permanently' attached!
As a single, I decided initially on a Designer home, without the implied restrictions of a courtyard villa neighborhood. In some respects, the villa style may very well suit your lifestyle, but it really is something that should be investigated!
Whichever way you go, please be welcomed to The Villages!
