Charleston is in general a laid-back, but sophisticated, city and has an old-South feel as does Savannah, GA. Most people in Charleston are helpful when approached in a polite manner. If a traveller speaks little English, Charlestonians are still generally willing to help as best they can. It is advisable, however, to at least learn a few key English phrases, and perhaps carry a traveler's phrasebook. http://wikitravel.org/en/Charleston (South Carolina)
