Yes, we did the Baltics this past August. I did a review so you may check that out for further information.
It was our fourth trip on the Sun, and she is one of our favorite ships. Very easy to get around on and a woooonderfully friendly staff.
We embrked in London, and I think the move to Copenhagen should be a plus. Although, the sea day was very nice for resting up after some busy days in London and preparing for a whirlwind in the Baltics.
Great trip. If you've not booked private tours for Russia, I highly recommend it. You will get so much more out of SPB if you do private
rather than ship's tours.
