anyone been to a concert in the easter series at the Festspiel haus in Baden Baden ? we have got tickets for concert there -Sir Simon Rattle and the Berlin Philharmonik Orchestra not opera and i wondered if we need to get dressed up . i have read on trip advisor that it is evening gown and black tie but i wonder if that is for the opera posh seats ? I dont want to get it wrong but we are flying out ryanair hand luggage only so if we can get away with smart causal i would much prefer to do so. thanks in advance if anyone has any insight into this
