Your hair dryer won't either HOWEVER, the plugs near the TV and desk did work and that's where I did my hair every day.
uh-oh do I have to bring a hairdryer too? I thought they had them there?
I believe hair dryers are prohibited as well.
Flat irons are fine, curling irons are fine, hair dryers are fine (the ones on the ship should be called "air blowers"
Irons AND Steamers are not allowed on any of the ships for safety guidelines. If you bring it and your SRH sees it, they will kindly keep it safe for you until the last night. There ar irons on the ship in the laundry room to use.
