Though most of the villas on the Resort are owned by private individuals, they are all managed by the Westin.  For example, your check-in when you first arrive is handled by the Westin.  Also, any Resort services that you may later make use of can be charged to your villa number and paid for when you check out, just as if you were staying in one of the Resort's hotel rooms.

As you can see from the photos on this page, the Resort property is beautifully landscaped.  In addition to all of the facilities and activities on the Resort, even just a stroll around the resort is quite enjoyable.  There are two lobbies on the Resort - One close to the main entrance and another near the Resort dock.
