Considering the Astron Hotel Altona in Hamburg?

Harbour cruise for next to nothing.... by tini58de
Instead of taking one of those very expensive harbour cruises (which are very interesting, too!!!), you might want to just take a boat that takes you from Landungsbrücken to either Altona or Neumühlen or even further to the other side of the Elbe river to Finkenwerder.
Line 62 is a perfect ship to give you an hour of relaxation and beautiful views of the houses and beaches of Hamburg.
Be sure to get one of those ships that accept your HVV ticket!
