There is a regular outlet behind the tv (two if you have a mini-suite) and also behind your nightstands for plugging in your chargers and other items. My wife agrees that the hairdryers are not that powerful, but still served its purpose.
WAS ON THE GRAND IN NOVEMBER, AND IT WAS THE FIRST TIME I DID NOT PACK MY HAIRDRYER. BIGGEST MYSTAKE I MADE. THE ONES ON THE SHIPS HAVE HARDLY NO POWER TO THEM. I HAD TO RESORT TO THE BEAUTY SALON FOR THEM TO DRY MY HAIR AND STYLE IT. WHEN I WENT ON THE CELEBRITY CONNIE, AND THE CARNIVAL LEGEND, THEY HAD GOOD HAIRDRYERS. WILL BE ON THE NEW CARRIBBEAN PRINCESS IN OCT. AND I WILL BRING MY OWN HAIR DYER FOR SURE. I LEAVED FROM MY MISTAKE
