We've decided to kill the Poland idea all together, although the three of us are Polacks..

Something along the lines of London-Paris-Brugges-Amsterdam-Bremen-Berlin-Munich--St Johann (Tirol)-Venice-Lucerne-Interlaken-Bern-Paris-To London

Using a busabout pass, and Hostels, and with thirty days, we can spend approximately two days in each place, but may pass through some places (Tirol) for instance, and stay in others for more time (Berline, Interlaken, Amsterdam)

And no puff puff in Amsterdam!

And June 13 to July 13...woops
