Hi Steve, pretty much what Ken says about Laboe applies to the XXI in Bremerhaven, you pay an entrance fee of 3 Euro, tour everything, photograph anything you like and can buy lapel pins and little booklets at the entrance. Have visited twice and liked the interior very much. While in Bremerhaven, your client should also visit the Seefahrtsmuseum which is situated nearby. There's a very handy bus service from the railway station to the seafront every half hour during the summer. Tickets must be bought beforehand and cancelled inside the bus, but conductor can help if right change is available. Regards, Io
