It's recommended to have a car for this vacation, as many of the activities are located outside of Sandusky. Travel costs may vary based on the distance traveled and gas prices during your trip.
If you have more time, consider adding a day trip to Cleveland to visit the Rock and Roll Hall of Fame or the Cleveland Museum of Art. If you have less time, consider skipping one of the islands or the Merry-Go-Round Museum. Also, be sure to purchase tickets to Cedar Point and Soak City online in advance to save time.
