I'm planning a trip with my mom who would like to visit either Charleston or Savannah. She's 83 years old; she can walk fairly well, but she gets tired quickly and often needs to rest. She often uses a cane. I wonder if Savannah or Charleston is a better destination for us? We will travel there by Amtrak, we've both taken the train before so we are aware of pros and cons of train travel. My question is more about the ability to get around once we arrive. Thanks in advance for any advice.
Also, we'd like to go this October, when it's not so hot. We'd rather not wait till next spring.
