To plan individual excursions on your own, it is important to be familiar with the conditions at the various ports. Some ships dock very close to the city, making it easy to walk into town. Other ports are industrial ports where entry to the port area is prohibited, and shuttle buses are provided to take passengers into the city. Lastly, there are ports that are simply located far outside the city. In these ports, you will often have to rely on the usually paid shuttle buses. To make your planning easier, I have compiled all the important information about the different areas here. These are sorted by travel regions to help you navigate more easily.
