I strongly suggest that you buy a guidebook in order to appreciate just how excellent Bermuda is and to get a feel for what can be done there. Bermuda is clearly a cut above anywhere you might have been in the Bahamas or the Caribbean.
That said, King's Wharf is on the extreme end of Bermuda; please do yourself a favor and get on a wonderful pink bus, or in a taxi (all have drivers proud of their home), or take one of the ferries to destinations around this island.
Most cruises to Bermuda are there for several days; I am assuming that you have one of these multi-days itinerary. It would be a shame if you did not leave the King's Wharf area; you will not experience Bermuda.
