I saw a review on this ship and I believe that person who wrote it cruised on a different ship. A lot of what he/she said was not accurate.
I sailed from Nassau, Bahamas. We were able to board one or two days before the ship sailed for $100/night, which is a lot cheaper than going to a hotel and paying for our food for the day. Coming from the west coast, it was better for me to arrive early but I should have come 2 days early instead of one so I would have had more time to recuperate from the jet lag (3 hrs). Boarding o the MV Explorer was the easiest boarding I have ever had to experience in my life.
Out of 10 ports, I had not seen 7 of them before so I was excited to see them. I was impressed by the cleanliness of the ship. It is the fastest ship at sea and they explained to us that when we feel the shaking of the ship is when they engage the other gear (or motor) but it lasts just a minute or so. Many times, I thought we were not moving because the ship was sailing so smoothly. I had to look outside my window to make sure we were moving.
Great Location, no noise, mid-ship, easy to get to from anywhere on the ship. Shower stall was a little larger than the ones on big ships.
