A New Jersey family was heading home Friday after an unforgettable vacation in which a grandmother, her son and grand-daughter drove around south Florida, lost, for 81 hours, authorities said Friday.

John Thomason, 72, spent three days waiting for his family to return to their hotel after the trio left for a sightseeing tour Monday morning. He called police and reported them missing when they failed to return that evening.Detectives treated the group as "endangered" because Thomason told police his wife, Rose Thomason, 69, is a diabetic who suffers from manic depression.
