Stray Too Far from Port

If you’re the independent type who would rather trade organized shore excursions for exploring on your own, keep the following in mind: Many ships sail around 6pm — and if you’re in a major city on a Monday through Friday, that likely means traffic jams — so plan to explore the sights farthest from port first, and work your way back as the day progresses. If not, you'll find yourself too far away as all-aboard approaches, and you may even miss your ship.
