I hesitate to disagree with helpful advice, but please DO get a notarized parental consent from both parents. I child will get "emergency life saving care" in an emergency from an emergency hospital, but many if not most urgent care facilities will not treat a minor without authorization. We live in too litigious a society. Have a wonderful time, we've taken our grandchildren on many a road trip and they have created wonderful memories for all. And yes, we have been to a few ER's over the years, always with happy endings.
