Hi Lisa,
Welcome to LCT! Thanks for posting. You'll love the Navigator and the Bermuda cruise is wonderful. Because the ship docks overnight, the shipboard activity is a little different. People go off the ship to eat and be entertained in the evening. There are some Bermudian laws that don't allow the production shows on the ships to encourage that. To compensate, there was musical entertainment onboard those nights. We had a great time in Bermuda. We were really impressed with how clean everything was on the island. It was very beautiful, but, so is New Hampshire!
Please feel free to ask any questions you might have. There are a number of us here who have done that itinerary. We loved it.
