Yes, you can. When a cruise ship stays overnight in a port such as Bermuda, the ship essentially becomes your floating hotel. Once the ship has cleared local authorities on the first day, you are free to come and go as you wish.
The gangway remains open throughout the night, which means you can head into town for dinner, enjoy nightlife, or return late without any restrictions. If you want to get off the ship very early the next morning, you can do that too. As long as the ship is still docked and the gangway is open, guests can move on and off freely.
This flexibility is one of the nicest perks of an overnight port stay. It lets you enjoy the destination at your own pace while still having all the comforts of your stateroom waiting for you.
