Just repeating to you what an engineer type on Crown Odyssey told me about it a few years back. Actually I think on a lot of ships the hair dryers are supplied, and they are 220V. And I have been on ships where several cabins on one deck lost their 110 at once due to overload and circuit tripping. On one cruise it was happening every day until the engineers finally fixed something across the hall. This may not be an issue on the newer ships.
Landlocked in Denver, but cruisin every chance we get.
