I will be in Europe next August and am just starting to think about the big picture for the trip. For now I want to uncover any must-do things that either require advance booking or are only a once a week occurrence. Let me know if you can think of any.
Also, is it possible to keep a flexible itinerary and only book lodging a few days in advance as we head towards Brussels from Amsterdam.
We are experienced off the beaten path travelers with 2 young teens if that helps. This is our first time in Paris.
