don't the bathrooms come with a built in hairdryer much like the hotel rooms?
If you're picky, bring your own.
The in cabin dryers apparently vary in quality from cabin to cabin. DD has long, very thick hair and loved the in cabin dryer better than the one she has at home.
However, it really is moot, since 15 minutes outside in the humidity and wind, and all the styling will be undone.
It was like some crazy mixed up vacuum cleaner hose.
