My husband and I are planning to vacation with some friends at the end of the september. Maybe around labor day for a week. The options we are considering are Hilton Head, SC, Outer Banks (maybe Emerald Isle?), or Block Island. Our kids will be around 19.5 months by the time we go. Anyone been to any of these places with little ones? Do you think there is one we definitely should do over the others? Love any input thanks!
