We had a marvelous time on this cruise. It was our first time on the Explorer, after having sailed on the Voyager (once) and the Navigator (World Cruise 2017 and Cape Town to Rio 2018).
Things got off to a bit of a rough start at the Copenhagen Marriott. The morning of embarkation the restaurant was swamped with a very long line for breakfast, and bus #1 delivered us to the wrong ship in the port! It was easily rectified as the Explorer was right next door.
We loved the itinerary, even though it was port intensive. Every day was a new adventure! We especially liked our 3 days in Saint Petersburg, including the Grand Imperial Evening of the Tsars, and the fact that we hired a private guide and driver for day 2.
Our cabin was perfect! The amount of storage compared to the Navigator was amazing. We had drawer space that we never used! The bathroom was beautiful, and one of the best showers we've ever had in a hotel space. Lots of outlets too. We also loved the size of our deck. This was our first cruise without a butler, and our stewards did a wonderful job in our cabin.
