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.
