Euro Trip '07

Me and a few mates are going on trip around Europe for a month via train.
The tickets cost £285 each and cover these places:
Finland, Norway, Sweden, Austria, Denmark, Germany, Switzerland, Czech and Slovak Republics, Croatia, Hungary, Poland, Bosnia-Herzegovina, Belgium, France, Netherlands, Morocco, Portugal, Spain, Greece, Italy, Turkey, Slovenia, Bulgaria, Macedonia, Romania and Yugoslavia.

The only place we definately want to go to is - Amsterdam.

What other places do you recommend we visit?

Also how good is Oktoberfest? as me and a mate are thinking about going for a few days.

Thanks
