i'm travelling alone to andros for a few days. i want some good, relaxing beach time and snorkeling/exploring. south andros and mangrove cay both sound great, but i can't tell if there's much there besides the hotels i'm looking at (nathan's lodge and seascape inn). are there places to walk around, explore, meet people? other restaurants/bars? i'm not looking for anything touristy. anyone have experience in either of these places?
