My husband and I had been to Charleston before so we didn't take and tours. He and a friend went to Fort Sumter and I went with my friend to the open air market. Afterwards we met at Magnolias for wonderful shrimp, sausage, and grits. Charleston is a great walking city and the port is 2 blocks from the market and plenty of shopping. If you don't want to take a tour, just start walking, you can't get lost as you can see the ship from anywhere in town. The market place is fun and full of "stuff". Look for the women making baskets which are beautiful.
Newport is fabulous when the weather is nice. However, on our cruise the weather was miserable - cold and rainy. Again, this is a wonderful walking town and a must is a visit to the mansions. Also, if you really like a good walk, go to the Cliff Walk which runs along the ocean and behind the mansions. There a many many great restaurants in Newport and it's hard to go wrong. The Black Pearl is one of my favorites.
We had to tender in Newport and seeing the ship at night in the distance was a treat.
Bar Harbor is somewhat like Newport. Many beautiful homes, great restaurants and beautiful scenery. We took a tour of Acadia Park which was delightful and then just stolled around town. This is a great place to get a lobster lunch at a much better price that if you take a tour that includes a lobster lunch.
Ces't tres belle! It's beautiful and if you can't get to Paris, this is the next best thing. We had 2 days in Quebec which was wonderful. It gave us time to take a quick tour and then spend time strolling throughout vieux (old) Quebec. Be sure to eat off the ship. There are many great places to shop or eat. Be sure to visit Rue Petite Champlain. It's within walking distance from the ship. There is a free bus that travels around Quebec that is easy to use if you don't want to walk. A great place to visit - don't stay on the ship.
