You can plug it in. Why couldn't you??? Just beware most cabins have 2 plugs. One near vanity, desk in cabin and one in bathroom. At least I think they ahev 1 in the bathroom but I always use the one near the vanity thingie. Maybe the newer ships have irons but the Jubilee does not neither do the fantasy class ships. I am not sure if the suites do but the inside and outside rooms do not.
