The kit lens would work for the shots you anticipate taking.
You could consider a lens with a longer reach, like the new Sigma 17-70mm lens.
Both lens would allow you to travel light, too.

Sailing to Cuba in late Jan. Will have 7 days there and want to photograph people, cars, street scenes (Havana), sailboat races and everything else. Have a Nikon D300 with 18 - 55 kit lens. Any suggestions on an additional lens to take?
