To those who helped me narrow this down, thank you! I've just purchased my plane tickets. I fly into Brussels and leave from Trondheim, Norway, with 22 nights to spend on the ground. This is happening in May 2016.
Now I need to figure out my flights within Europe. Here is my basic plan
Nights 1-6 in Belgium (maybe all Ghent or divided between Ghent and another city?)
Nights 7-12 in the Netherlands (maybe 4 nights in Amsterdam and the other 2 nights in Delft or Rotterdam?)
Fly Amsterdam to Oslo
Nights 13-15 Oslo
Nights 16-18 stops along the way to Bergen
Nights 19-20 Bergen
Fly Bergen to Trondheim
Nights 21-22 Trondheim
I know there is endless debate and no clear-cut winner on the best Belgian city to stay in, so I won't ask for advice on that. But is my basic allocation of time sensible (6 nights Belgium, 6 nights Netherlands, 10 nights Norway)? And two nights in Trondheim at the end makes sense?
Other than the two flights, I'm planning on taking trains and not renting a car.
I'll be 60 at the time of this trip. Active and healthy, love hiking and nature, also love history, art, architecture, history, and culture in general, and very happy in smaller towns as well as big cities.
Any other thoughts or suggestions on this itinerary are most welcome. Thanks!
