We are looking for a few days of quiet in a vacation rental with direct access to a quiet beach over the xmas/new years holiday. We are considering Jekyll or St Simon or Tybee... but have a million questions! Will these places be shuttered over the holiday? On which ones can we walk our (leashed) dog on the beach? Recommendations for a rental in any three? We just want a relaxed vacation with beautiful beach, a walking area, and some decent restaurants. Help!
