Hi Iris
I did publish your question and reply to you yesterday but both messages seem to have disappeared. I'm sorry about that.
The tour doesn't include an opportunity to see a ballet in St Petersburg but it may still be possible. I would suggest that you do some more internet research and make a note of any performances you would like to see. Then, when you meet your tour manager, you can ask him for advice on what's possible and how to go about it. Hopefully you will be able to see your ballet but don't be too disheartened if not - Russia has many other incredible sights.
Kind regards,
Olly, your editor
