Hi Jennyf,
I did this tour in September 2016 and thoroughly enjoyed it; as jonah has said, I did leave a review which you can find in the relevant section. Looking at the brochure I see that the hotel in Moscow has been changed since I went, so unfortunately I can’t comment on that. However, the Taleon Imperial in St Petersburg is wonderful and remains one of the very best hotels that I’ve ever stayed at.
The itinerary remains largely unchanged since my visit, except for the addition of afternoon tea with a Russian ballet dancer on day 6, which should be an interesting experience.
As for adapter plugs, I would suggest that you look on the internet to confirm what you’d need. I can’t remember buying a special adapter for my visit so I’m thinking that it may be a standard round two-pin plug, but don’t quote me.
Russia is an amazing and interesting country to visit and I’m sure that you’ll enjoy it. Have a wonderful time.
Cheers
Mike
