EuroTrip 2017

EuroTrip 2017 suggestions wanted!

The planning has commenced! I’ll be Europe bound in just a few months and I’m looking for suggestions on must see locations and must do excursions. 

Between Germany, Czech Republic, Greece and the Netherlands, where do I need to go??? 

Send me good stuff cause if this goes well, I can’t promise I’m coming back cause… ‘Merica ?
