My husband is 72 and I'm 68 and It was our first cruise. We enjoyed every minute of the cruise. The cabin was very nice and comfortable, although we were surprised that there were no shower caps, no body lotion and no liquid soap. They did our room twice 1-day, but did not fold our pyjamas.
The excursions were very expensive. They said that all nations needed visas to St. Petersburg and that was incorrect information.
The embarkation and disembarkation were very professional and smooth. Bravo!
