The beach is not in North Charleston. You can go to the isle of Palms which is about 20-30 minutes depending on the traffic!
We stayed at the Red roof. No comparison to the quality experience you get from Hampton's rooms and good breakfast!
This hotel is not near the Beach as the other respondents have written. It is also surrounded by cheaper hotels such as Motel 6, Red Roof Inn and some Mom and Pop hotel. These hotels are cheaper and literally less than 2-3 blocks away.
Approximately 25-30 minutes depends on the traffic to Folly Beach
