One of the 12 Biggest Travel Mistakes You Think You’re Too Smart to Make (by Wendy Perrin in the Condé Nast Traveler)

Failing to visit the one place on your cruise itinerary that was your top priority. Many people choose a cruise for that one port of call they’ve always dreamed of seeing. Then, thanks to bad weather, rough seas, a labor strike, a safety threat, or some other unforeseen reason, the cruise line cancels the port call—with no possibility of a rain check (and no compensation, either). If your life’s dream is to see the Colosseum or the Acropolis, book a cruise that starts or ends in Rome or Athens, rather than stopping there mid-cruise.
