How does a cruise to bermuda work with the excursions?

joanaa asked:

So im going on a cruise to bermuda this summer. What happens when the ship docks there. do you take all your stuff with you to a hotel for a day or something?? can u go in and out of the boat whenever you want during that time? If you don;t pay for the activities like snorkeling and stuff do they dock right next to the beach? Can you go into the ship whnever to eat or sleep? Basically anythign i need to know kinda new to this thanks!
