About two and a half hours. You do not need to get all dressed up if you do not want to.

We bought ours on line and I think I just showed the email on the phone to the girl on the desk

Hello there! My husband and I are not opera fans either, this was our first one. The seats are limited so wherever you sit you will see and hear everything! It is so intimate - I loved it! We had a glass of Prosecco at the first interval. The seating is spread out all over each room so you will be happy with your seating each time. Enen if you are at the back for the 1st act, you can easily see and hear it all and then after the interval, make you way to the front in the next roomBut the actors/sibgers/misicians move about too. Do not stress over seating as it really is not an issue.I do not speak a word of Italien but read up on the story of La Traviata beforehand. I was so moved by the acting and singing+music that I was literally in tears at the end.You will love it! Enjoy!

we were there a few days ago and like someone mentioned there were aircon units in some rooms, however they were not on and it was very hot!

The show is included on your "membership."

Sorry I’m only just answering. Yes, you choose your seats when you arrive, there are only about 30 people at each performance. Each time the scene changes, you move rooms and move seats. It’s a very intimate setting and a fantastic experience, enjoy every moment.

I have just double checked. In 2014 I paid €70 per person and this included ‘membership’, entrance to the show and a free drink. Yes we had to fill in the ‘membership’ forms at the desk as we entered and hand over the ‘membership’ fee (€70 each). The show was then free. We like opera , we are not opera snobs. We loved this show. I hope you have a magical time.

Being so close to the performers adds greatly to the experience , coupled with the lack of formality i think this would be ideal for a young person. Get there early for best seats and skip the glass of prosecco for better seats after interval
