This cruise was a very good value, with a great itinerary. We started in Copenhagen and spent two nights at the SKT.PETRI hotel, which is very centrally located and one can walk all over easily from there. They also had the best hotel buffet breakfast I have ever had (came with the room). Highly recommend this hotel. The Baltic sea was very calm on this trip. The food was excellent, as was all the service. In St. Petersburg, we took a two day tour with Ulko tours (signed up with Viator) and saw so much over two days in the most beautiful city and outskirts. Saved a lot of money using Viator. Just be careful in St. Petersburg subway or any crowded tourist areas, as pick pocketing is rampant.In Oslo, it was great to see Vigeland Sculpture Park and art museum tour ( ship excursion). Stockholm is beautiful (ship excursion) also. In Warnemunde Germany, we took Mega Mecklenburg tour from Friends of Dave Tours a great value and excellent tour and guide. The Regal Princess is a wonderful large ship that never felt crowded to us and I would highly recommend. Great overall experience.
