The Star TA changed Barcelona to Tarragona this year. I researched the Port of Tarragona and thought we’d be fine. It turned out there were no services at all. Be aware there are 2 different Train stations there. https://www.porttarragona.cat/en/ Almost no Taxi’s available. People were lined up waiting for a very long time. We chose to walk out of the Port. We were told we could not do so. There was no Port Shuttle available even though the Port of Tarragona website said there was one so be aware if you have a plane to catch. The ship did offer airport transfers, probably be wise to take one.
