Very quick trip to Germany, France, Netherlands
I desperately need to advice of people well travelled in Germany, France and Netherlands. I may be going to a conference in Essen, Germany and if I do (paid for by work) then I want to tag on 7-10 days of travel around the area. I can't do more as I won't want to be away from DH and DS for longer. I am thinking of flying into Paris or Frankfurt then going to Essen for the conference (3 days) and then a few days in Germany, a few in Netherlands and a few in France before flying out (again either from Paris or Frankfurt). I am on a strict budget and trying to navigate the rail system which seems hideously expensive. But I also want to know what are the things that are unmissable for these countries? Please help!!!
