Hello George and Bev, and welcome aboard! I think you'll find both U.S., 110, 60 cycle outlets, and European type plugged 220, 50 cycle outlets, both in the bath and in the cabin. There is usually only one of each of the outlets, so that's why they suggest an extension cord, with additional outlets, if you need to plug in multiple devices. Hope this helps, and have a GREAT cruise.
