My husband and I will be in Savannah on April 19-21. We were there for a day and a half a few years ago, and did the "on and off" tour which we really enjoyed. We were hoping to visit some historic homes/plantations this trip, and would like some input into which would be the most recommended. This is Easter weekend, so wondering if that would make a difference in what's opened and what's not. As we leave Savannah, we are headed South towards Valdosta. Are there any other small historic towns / plantations along our route? Thanks for your help!
