bus transportation from Hamburg to Berlin

Alan, go to Berlinlinienbus.de (www.) click on the little British flag on the top right for the English version. It looks like they have several departures a day - 19 Euro one way being the cheapest ticket. Seems the trip takes three hours and 10 minutes. Sounds like a terrific deal and takes you right downtown.

With a Dauer-Spezial fare (adv purchase, non-refundable) you can go from downtown Hamburg to downtown Berlin via InterCityExpress (ICE, yeah, that's a train) in 1hr 39min for as low as €29.
