If your parent,s don,t mind the coach travel maybe they would like JERSEY fantastic scenery, and it,s flat, lovely places to visit,which some coach firm,s will include, not forgetting the lovely weather,very nice people,We have alway,s stayed in St,Helier the capital so your not far away from everything,and yet it,s not to overbearing.
Hope your parents have a wonderful time where ever they go.
