I'd like to thank my awesome Dad, whose generous Christmas present is helping us fund our next trip. Thanks Dad!!
We know we will hit at least two cities on this trip, and are aiming to run through a third as well, all within less than a week. I'll send a yet-to-be-determined prize to anyone who can guess the three cities. One guess per person, please. :) Here are some vague hints: All three cities are in Europe, none of them are in Germany, and neither of us has been to any of them yet. Our itinerary is as follows: Overnight train to city 1, 2 nights in city 1, day trip through city 2 on our way to city 3, two nights in city 3, and an overnight train back to Heidelberg.
