Carol, it's St Lucia. bbeach... It depends what you are looking for. Rodney Bay can be lively and there is plenty of choice of restaurants and activities. Marigot is generally quieter and not so much there. Personally I prefer Marigot. Driving... All the Windward and Leeward Island roads are chaotic, St Lucia just has the added difficulty (if you are used to driving on the right) of driving on the left. I don't find it a problem switching.
