We are planning a six night stay in Charleston area in early October. Going on to Savannah for add'l couple days. We are two late 50ish couples, who plan on taking in Charleston during the daytime and relaxing at a vacation rental on one of these islands. We love nature, beaches, bike paths, sitting by the pools, etc. Heard the resort pool on Seabrook is closing Oct. 1. Is Seabrook Island only accessible with a resort pass? How about Kiawah Island? Could we stay on Seabrook and still enjoy Kiawah? Ideas please on where to stay please. Are five days in Charleston and two to three days in Savannah enough? Thank you so much.
