I clipped this from the 2nd page of one of our reservations "Confirmation Guest Copy":
"Please refer to www.ncl.com/about/cancellation-fee-schedule for our Payment and Cancellation policy. Norwegian Cruise Line highly recommends that every guest purchase some form of travel protection. For your convenience, we offer an optional BookSafe Travel Protection, however similar plans are available through other sources. To review the state-specific (based on your state of residence) terms, conditions, and exclusions with BookSafe visit www.ncl.com/freestyle-cruise/booksafe. For questions regarding your BookSafe Travel Protection, please call 1-800-722-5672."
