My family of 5, with three children - 5, 7, and 9, are hoping to take a vacation to Charleston in early August. I am not sure this late into summer if we can get reservations anywhere, but if so, we would appreciate any advice on things to do, see, or places to stay, eat. My husband is a history buff but we would have to balance the historical sights with beach/relaxation for the kids. We would also love to take a dolphin cruise or fishing charter but not sure that would be in the budget. Thanks so much!
