1. What to do if it rains
WeatherVery hot and sunny though like the U.K & Normandy/Brittany, this is not always the case. Jersey does have the highest hours of sunshine in Great Britain though this may not always seem so. It is southern Britain after all - not the south of France.
HolidayVery enjoyable. It is a great place to come by yourself but is even more enjoyable with a friend or family. The people are friendly and with Portugese and Polish, Thai and Kenyan you get a slightly cosmopolitan feel.
