voltage adapter

The first question is if you need a converter at all. What devices do you plan to bring? If it's something like a laptop or iPad, you don't need a voltage converter, only an outlet adaptor. I found that Denmark uses a slightly different recess size for electrical outlets compared to the rest of Europe. The standard Europlug adaptor will work, but if you're worried about safety, just ask your hotel in Denmark for the proper adaptor. If you plan to bring something like a hairdyrer or curling iron... more complex story.

If the devices you want to plug in are dual voltage (110-240v), you only need a Euro plug adapter, not a voltage converter. The only cruise I ever took was a river cruise in China, so I don't know about Royal Caribbean.

Paula, Just to clarify the terminology, are you referring to a Plug Adapter or a Voltage Converter? The first thing you'll need to do is check EACH electrical device you'll be travelling with to determine the Input Voltage. That will determine whether you'll need only Plug Adapters or a Voltage Converter as well. If these state "Input 100-240 VAC, 50/60 Hz", then you'll only need Plug Adapters. For information on the type of Plug Adapters required for Denmark, check magellans.com as they have lots of good information on their website.

Hi, Paula-- I've been on Royal Carib cruise ships and did not need an adaptor for anything at all. BTW, there are well-stocked (but not cheap) shops on the ships with every sundry you might need. Have fun.
