Thank you for the terrific travel logs. We are going on the Black Sea cruise that departs on August 30th. Which ports would you take private tours compared to Regent tours? We are already signed up for the Regent tour to Bucharest. What ports are best to do on your own(walking)? If we do a private tour in Sochi do we need our own visa's. We had John Barron as Cruise Director in SA last Feb. He was great. We have never been on the Navigator before and after reading all the reviews are looking forward to the food. Maybe we should start some serious dieting right now.
