The high season follows typical beach-town cycles, with June through August and holidays year-round being the busiest and most costly. Mid-April, during the annual RBC Heritage Golf Tournament, is when rates tend to be highest. Thanks to the Lowcountry's mostly moderate year-round temperatures, tourists are ever-present. Spring is the best time to visit, when the weather is ideal for tennis and golf. Autumn is almost as active for the same reason.
To get a good deal, it's imperative that you plan ahead. The choicest locations can be booked six months to a year in advance, but booking agencies can help you make room reservations and get good deals during the winter season, when the crowds fall off. Villa-rental companies often offer snowbird rates for monthly stays during the winter season. Parking is always free at the major hotels, but valet parking can cost from $17 to $25; the smaller properties have free parking, too, but no valet service.
