This year I'll probably there again for 2 days with a group that has more planning than me so I'm just along for the ride for specific things they are looking for. Other than that strolling along and sitting down whenever something seems interesting is my approach. If there is enough play-tables for Spiel des Jahres /Kennerspiel des Jahres surely they'll be checked out although Dorfromantik I already played there last year.
