Short answer to your question: Nothing

On the other hand, have you ever been to Savannah? It's a half-hour away...not exactly inconvenient. Charleston is a long haul from HH.

Savannah's got lots of good food and drink downtown, friendly people and plenty of history.

I find Hilton Head to have the worst cuisine in the Carolinas, so on days when you can't golf or do the beach scene -- I leave the island. Even Bluffton is an improvement.
