Yes, need converters on MOST European ships
Hope you have a GREAT first time,remember these ships are much smaller than ocean ones.And rooms are SMALL,in comparison.Esp.the bathroom(need to go thru locks so must be certain width).
Entertainment is not lavish,but fun .Food is usually good,,not 5 star like ocean...so dont compare.Great for what they DO provide.Just DIFFERENT.
I love them,,such a great way to see the inland cities.So much better than bus tours and easy to manage(unlike private cars).
Any particular question,will be glad to help.I just got off AMAcerto in June and going on AMAlotus(Vietnam) in Dec.
