for 230 v do I need an adaptor for US hairdryer?

Barbara, you need a converter to convert the electricity from 230 down to 110 and then an adapter for the end of your plug to make it fit into the socket. Most converters come with several different plugs for different countries but depending on what country you are in, sometimes the converter boxes don't fit into the European sockets, lol. For example, I was in France and the sockets were recessed into the walls so I couldn't use the converter box.

What I find best to use is Conair blowdryers and curling irons. They have several models that you can just switch a switch on the them that changes the 110 to 230. You can find them at any store like Walmart for under $20. Then all you need is an adapter for the end of your plug.

For items like battery chargers that don't have a converter built into them, you will need to use one or you will fry your items.

To answer the question in your subject title, I dunno :)

Rash guards look like this:


Usually made with spandex, they're designed to fit snugly to protect you against 1) the sun (SPF built in) and 2) ocean creeply/crawlies like jellyfish. They were originally designed for surfing and to protect your skin from developing rash from rubbing against the board (hence the name)

Barbara, there is a hair dryer in each stateroom. And there are 120v outlets in each stateroom, so you don't need to get a voltage converter or a plug adapter.

We only needed our voltage converter for our post-cruise stays at the Pearl Resorts.

When we're going to be snorkeling for long periods we use our Henderson "skins". They are long sleeve and full length with stirrups under the foot. Great protection against the sun and jellyfish etc. plus they keep me from getting chilled. I'm fine for 30 minutes or so in only swimsuit. You'll only see a few of them in use in FP but I'm a comfort over fashion gal.
