Peggy, you might want to edit your post to say that you are just "Peggy from Pennsylvania." Giving your last name and town on a public forum could be a tip-off to those who are interested in which houses in your area are empty on which dates! I just cringe whenever I see someone do this.
That being said, you are going to have a wonderful time on Russia Revealed. We were there at the same time last year. It is a great trip, with lots of interesting sites, history lessons, scenery, art, shopping, and food! The time on the ship is peaceful and lovely, St. Petersburg is a wonderful city, rivaling Paris, and Moscow is large and interesting. Have a good time!
