Norwegian Dawn Cruise to King's Wharf questions?

We have booked a cruise to King's Wharf Bermuda. Its the only port of call. Im excited to see Bermuda but haven't herd great things about the port and things to do there. Ive cruised with Disney in the past and loved the port of calls in the Bahamas. I want to make the best of this Cruise and want to know any tips for activities. What are the must sees. I really don't want to spend my vacations spending money on transportation. I love having access to the ship when ever I like... we are docked for 3 days. Anyone have any tips... Must sees??? Day trips???best deals and prices..? thank you
