Narrow roads, wide busses, driving on wrong side of the street. Many tourists get into wrecks with them. The bus system is excellent and easy to use, and the ferries are great to get to/from Hamilton or East George.
I think cruises now shop way out on the point so it's a hike to most places, but worth it. Bermuda is a perfect palce to go for a long weekend and relax. Not far, pretty.
Of course last time we were there my wife had a heat stroke on said ferry and that wasn't fun. It can get CRAZY hot there in August.
