Yes they are american flat pin plugs, get them before you sail as the ones on sale in the ship's shop are, incredibly, european round pin types that are of course useless on this ship....
Hairdryer is provided your not allowed irons travel kettles etc for safety reasons think its American plugs at least thats what the Island Star was.Beach towels are also provided you can also take them of ship .
Absolutely no irons - if the cabin stewardesses even get a whiff of an iron in a cabin it is confiscated. The hairdryer supplied if very weak but OK if you have short hair. If you are bring your own then make sure (as with all appliances) that they are dual voltage. The adaptor available on board ( or in your local shops) will only adapt the plugs but will not transform voltage which is US. So if you have dual voltage appliances with an adaptor you will be OK but if you only have the adaptor and require a digital camera or mobile phone charging then take the chargers to Guest Relations and they will charge the items for you - this is on a first come first serve basis.
Sometimes it is worth looking in the corridors outside of the cabins as these (occasionally) have European power points with a built in transformer.
Thanks very much for your help and advice, do you know then if we are not to use irons are we allowed to use hair straighteners? your help would be much appreciated.
I've taken my straightners, and left them out for the whole holiday and there wasn't a problem. I just made sure I left them out where they couldn't touch anything or roll off while hot. Our steward was fine about them.
In your cabin there will be a hairdryer in the drawer irons are not allowed if you need anything ironed there is a charge, it is a flat 2 pin plug that you use , towels [orange] are provided for the ship pool i am not sure if you can take them off the ship but if you loose them there is a 10 pound charge each if I were you and expecting to go to a beach I would buy a cheap one and leave it behind when you leave, better than a 10 pound charge if it gets lost, i used my hair straighteners they worked well and nothing was said to me.
Did I not once read on this website that if you unplugged the cabin TV then that has a 240 Volts socket ?
In addition there is a 240Volt plug in the corridors but at a ratio of about one to every 10 cabins from memory - travel irons are not allowed and nor are kettles from memory.
