So I am planning a christmas river market cruise for the week of Christmas (leaving around Dec 21) for this year. It will be me (25), my parents, and my brother (16). We have done around 10 "normal" cruises mostly with Holland America (our favorite line) but have NO experience with river cruises. I have read a bunch about them but wanted to know what you all thought about which itinerary to do ( The Rhine v The Danube) and which line you think is the best. Also any tips about anything with river cruising, excursions, anything would be supper helpful!
