Hi! I have just come back from a trip on the Voyager. You will love it! There are both US and European plugs in the rooms. You will need a European adaptor (two round prongs) for the hair straighteners. The US adapters are fine for recharging phones etc, but the EU one is a must for the straighteners. I took one and they worked perfectly. There is a hairdryer already in each room in drawer of dressing table. Have an awesome trip! If you are early risers, I recommend getting up early for the sunrises - they are spectacular
