Our family of five had plenty of space in the rental and enjoyed our month long stay. Highlights: Super spacious, well-stocked kitchen, nice appliances, reliable WiFi, excellent cable channel package (we were happy to catch some Big10 sports), quiet and safe neighborhood, lovely view from the deck, very kind hosts and Palmetto Dunes is a nice central location on Hilton Head Island.
One thing to note is that the pickleball/tennis court rental fees are included, but equipment is not (though it is possible to rent the equipment at the facility). There is a pool right in the neighborhood, but the beach access was a bit of a jaunt.
Regardless, we had a great time and definitely would stay again. Highly recommend.
