We are property owners/residents of Kiawah Island and have been for the past 16 years. If you are wondering if it is easy to make friends/relationships on Kiawah..the answer is NO. There are so many options for making friends and whether you live here 12 months out of the year or less than that, you can meet people in so many ways. Golf and Tennis of course, but there are numerous clubs and organizations generated by the POA on Kiawah. You can volunteer in and around the area as well. After 16 years, we have never ever had a problem with this sort of thing. On my street most people are full time owners and if they leave it's few a couple of months during the hot summer.
Hope this answers your concerns if you have any.
