Hello, we are soon setting sail on our first cruise since the pandemic (YEA!). One of the stops is Charleston. We have never cruised here before. We will arrive in port at 8 a.m. and have signed up for one of the excursions but it doesn't start until mid-afternoon. Is this this the type of port where you can walk off the ship and walk to see the sites or do you need to take an Uber/Shuttle to go to points of interest?
