We will have a day in Slovenia from a cruise ship docked in Koper. My husband and I are fairly independent travelers and have driven extensively in France, Italy and Spain and are comfortable getting around as long as we can handle basic language. Can't stand the thought of being on a bus with 50 other people. Is it easy to drive to Lake Bled and our own boat excursion, etc.? I have read that most Slovenians are multi-lingual so can we expect to speak English in most places? Thanks!
