Looking to book airfare in the next few days for the above major cities in late August. Wondering if there's a major difference in which order we hit these cities given that the airfare is pretty close either way. I'm inclined to start with Amsterdam followed by trains to Brussels and Bruges before heading to Munich, either by plane or train with a stop in Frankfurt, for 3 nights in Bavaria. No real reason for choosing this order and can be persuaded to reverse it. I appreciate any guidance on this itinerary.
