Take a small outlet plug (maybe 3 outlets) with you and then you can use more than one item at a time such as a hair dryer and a cell phone charger etc. You can purchase these at any hardware store, K Mart, WalMart etc. Almost every cabin we have had has one outlet except the newer ships that have two by the desk. I think all of the Carnival ships have laundry rooms where for a fee you can wash clothes and they have an iron and ironing board set up you can use. Hope this helps.
