Jennifer Marx grew up in Michigan, where you can stand anywhere within the state and be less than six miles from a lake, river, or stream. Her shipboard experiences include two weeks aboard a sailboat as a crew member and nine months working aboard the sternwheeler "Michigan" on Lake Biwa, Japan. Her first Disney Cruise Line adventure lasted just three nights in October 1999, and since then has spent more than three months at sea with Disney.
