With kids, it depends on the day.
Anchor the experiential read to one specific room: the Dvořák Hall in the neo-Renaissance Rudolfinum, the Czech Philharmonic's home since 1946 and the main Prague Spring festival venue, where Dvořák himself conducted the orchestra's first concert in 1896. The acoustics are genuinely world-class and the chandeliered, organ-backed hall makes a Dvořák or Smetana programme a real goosebump evening — exactly what the generic candle-lit church 'best of' shows can't deliver. The catch: costumed touts on Old Town Square sell mediocre programmes in echoey churches at a premium, so the warning is the verdict — buy from the Rudolfinum (or the Municipal House) directly and the night is special; buy off the street and it's a tourist trap.
