Not opera goers but our family of four got to experience International level opera in our own box for under £100 in total, one ticket at home would cost more than that. Amazing value - the drinks and snacks were far cheaper than you'd pay in a UK cinema! We saw Janeck's Cunning Little Vixen a, shorter than average, rather bizarre story but was great to watch and amazing to listen to. We dressed up a little but the audience were a real mixture and some people were wearing regular city tourist clothing without looking dreadfully out of place. The box had three regular dining type chairs giving a clear but sideways view and a restricted view stool behind but this was perfect for my husband who was happy to trade a good view for the ability to stretch his legs when needed. Probably the experience most likely to get me back to Prague again ...what an experience!
