I can confirm that no-one has been on this tour as it is new for us and the first departure is not until May next year. However it is very similar in content to our standard Moscow and Saint Petersburg tour that we have been running for many years now, so we have plenty of experience with the visa process as well as the itinerary itself.
The webpage has details on the visa application process which explains in detail what needs to be done (please refer to the FAQs section of the tour page - link below). It does require you to personally visit one of the visa application centres, either in London, Manchester or Edinburgh.https://www.rivieratravel.co.uk/single- ... travellers
I hope that helps,
