I'm off on a mini adventure with my lad in a few weeks inter railing around part of Europe, we have a few days where we are after suggestions for things to see and do, we will be in each place less no more than a day.
He's 15 in to history, gaming and the macabre, so any suggestions welcomed.
The places we have gaps in our itinerary are:
Brussels
Munich
Budapest
Rijeka
Cluj-napoca
